Stainless steel and aluminum alloy are two very common materials in our daily life, which are used to make various products, such as stainless steel cabinets, stainless steel and aluminum alloy doors and windows, and other goods for daily use. So what's the difference between stainless steel and aluminum alloy? So let's take a look!

1. In general, the differences between stainless steel and aluminum alloy are as follows:

1.**Stainless steel is expensive, aluminum alloy is cheap;

2.Stainless steel has a higher hardness than aluminum alloy;

3.In terms of surface treatment, aluminum alloys are more abundant, including electrophoresis, spraying, anodizing, etc., and stainless steel is less;

4.Aluminum alloy with poor surface treatment will oxidize after a long time and will have marks; Stainless steel is relatively better, but the composition is not up to standard or the maintenance is careless, and it is still rusty;

on the Internet, invaded and deleted).

5.There are many bad manufacturers of stainless steel, mainly cutting corners in terms of material thickness and composition; Stainless steel finished products are more valuable, mainly depending on what material it is, 410, 430, etc. are cheaper than stainless iron, 201, 2 02 and other life is more commonly used, 304, 316 is more expensive, and there are many materials, depending on what you use in that aspect. As the density of aluminum alloy is about 2700k g mm3, while the density of stainless steel is 7900kg mm3.

The hardness of stainless steel is higher than that of aluminum alloy, and it is obvious that stainless steel is much more expensive, and in general, stainless steel is much more expensive than aluminum alloy.

2. What are the advantages of aluminum alloy doors and stainless steel?

Aluminum alloy doors and windows: Aluminum alloy doors and windows are one of the popular door and window materials, which can be designed according to the requirements of customers, such as push-pull, casement, overhang, etc.

on the Internet, invaded and deleted).

It is easy to shape during the production process and can meet the needs of consumers at different levels. Aluminum alloy doors and windows have the advantages of durability, fire and moisture resistance, not easy to rust, corrosion resistance, good sealing, etc., and are generally used in buildings with high standards. Its disadvantage is that the cost is relatively high and the thermal conductivity is high compared to wooden windows and steel windows.

Aluminum alloy doors and windows are one of the more popular doors and windows in the market now, but because of the fierce and disorderly market competition now, many small shops fool customers with shoddy goods, so there are many quality problems.

Stainless steel doors and windows: stainless steel is one of the materials that many buildings like to use, which has good wear resistance, corrosion resistance, oxidation resistance, and the surface color is bright and bright, in line with the modern trend, very fashionable, and its own weight is light, which can effectively reduce the load of high-rise buildings.

Compared with stainless steel, aluminum alloy materials with the same volume and shape are much lighter, and stainless steel is stronger. Therefore, the material used for stainless steel will be thinner when used for the same purpose. Generally, stainless steel is made of natural color or gold, and there are fewer other colors, and the painted ones will lose paint.

Aluminium alloys are available in a wider range of colours. The acid and alkali corrosion resistance of aluminum alloy is not as good as that of stainless steel. There are many stainless steel grades, and the commonly used 201 to 304 will be prone to corrosion.

Aluminum alloy materials are troublesome to weld, so welding is generally not chosen. Stainless steel is relatively easy to weld, but the deformation caused by welding is large, and when the deformation is required, it is generally necessary to choose intermittent welding or no welding. The heavy stainless steel door has much greater vandal resistance than the aluminum alloy door.

There are: 1. Different materials, 2. Different prices, 3. Different specific gravity, 4. Different hardness, etc., there are also similarities, and they are not corroded.

The material is not the same, Foshan Shengwang doors and windows are available in both materials, you can take a look at the product introduction, the style is also there, the workmanship is also very fine, it is indeed a very good brand. If you don't understand, you can go down again.

The products used in aluminum alloys are: extrusion coils for the food, chemical and brewing industries, various hoses, fireworks pollen; chemical equipment; It is used for the processing of parts and components that require good formability and high corrosion resistance but do not require high strength, such as chemical products, food industry equipment and storage containers, sheet processed parts, deep-drawn or spinned concave ware, welded parts, heat exchangers, printing plates, nameplates, reflective appliances, etc.

The products used in stainless steel have very good formability and good weldability, and can be used as an ultra-high-strength material in the nuclear, aviation and aerospace industries. With a large amount of chromium and nickel, it has good heat resistance and oxidation resistance, and its products include: heat exchangers, boiler components, and injection engines.

1. **Different.

Stainless steel is expensive, aluminum alloy is cheap;

2. The hardness is different.

Aluminum alloy has low density, but high strength, close to steel, and good plasticity; Stainless steel is a nickel-chromium alloy that has a higher hardness than aluminum alloy.

3. The high temperature resistance is different.

Stainless steel can withstand high temperatures, with a melting point of 1200-1500 degrees Celsius; Aluminum alloys cannot withstand too high temperatures, with a melting point of 500-800 degrees Celsius.

4. The surface treatment is different.

The surface treatment of stainless steel includes surface brightening treatment, surface whitening treatment, and surface coloring treatment; Aluminum alloy treatment includes electroplating, spraying, anodizing, etc.

5. Different industrial applications.

Stainless steel has heat resistance, oxidation resistance, good formability and good weldability, and can be used as an ultra-high-strength material in the nuclear industry, aviation and aerospace industry; Aluminium alloys are used to process parts that require good formability but do not require high strength, such as chemical products, food industry equipment and storage containers, printing plates, nameplates, reflectors, etc.

1. The first difference between stainless steel doors and aluminum alloy doors is that stainless steel doors are made of imported stainless steel materials integrating R&D, manufacturing, sales and installation. The appearance is novel and unique, the functions are relatively complete, and it has an excellent quality reputation, which is deeply loved by the majority of people; It is made of high-quality aluminum profiles directly connected by rods, without welding in the middle, light weight, compact structure, packaging grouping, 100% quality assurance, strong and reliable.

2. Different weight, color, etc.; The color of the stainless steel door is relatively simple, and it is generally welded to the interface; Stainless steel electric doors are higher than aluminum alloy in terms of thickness and hardness, which can be said to be more durable. It is not possible to weld to connect, it is made of direct connection rods, so the hardness is also high, but it is not as high as the stainless steel electric door. The aluminum alloy electric door is not easy to rust, and the weight is not so heavy and relatively light.

3. The scope of application is different. Stainless steel electric doors are mainly used in various communities, banks, hospitals, hotels, business buildings, institutions, schools, factories, supermarkets, and many other fields. Aluminum alloy electric doors are suitable for banking, shop door industry, metal, machinery and machinery, electrical, chemical, communication and other industries.

Summary. Hello! Dear, I am glad to serve you, compared with aluminum doors and stainless steel doors, aluminum doors are better.

Aluminum doors** are on the higher side. The reason is: aluminum alloy has low density, high strength, more than high-quality steel, good plasticity, can be processed into various profiles, and has excellent electrical conductivity.

Which is better, aluminum door or stainless steel door.

Hello! Dear, I am glad to serve you, compared with aluminum doors and stainless steel doors, aluminum doors are better. Aluminum doors** are on the higher side. The reason is: aluminum alloy has low density, high strength, more than high-quality steel, good plasticity, can be processed into various profiles, and has excellent electrical conductivity.

The advantages of aluminum doors are as follows: 1. Excellent decorative effect: aluminum doors can be made into various colors and shapes, and the surface is glossy, the proportion of frame glass is small, and the aluminum doors can be made into large-size grids, which are very modern and beautiful, and can add luster to the building 2. Excellent performance

Aluminum door using thermal insulation profile and insulating glass, still has a good energy-saving effect and no frost, no condensation, can meet the needs of any high-end and high-rise buildings, is recognized at home and abroad in the high-end door products 3, good processing performance: aluminum profile can be processed into large size and complex cross-sectional shape, and high dimensional accuracy, aluminum door processing technology is relatively simple, easy to achieve modernization 4, strong corrosion resistance: aluminum alloy oxide layer does not fade, does not fall off, does not need to paint, easy to maintain, no maintenance.

If stainless steel is made of 304, its stability is much higher than that of aluminum, even if aluminum it is generally made of thick pipes, but its metal hardness is far less than the hardness of stainless steel. The door contains too much metal, and if it is stretched for a long time, his frame is easy to deform, which is more common.

However, aluminum is more resistant to corrosion. If stainless steel wants to achieve the same corrosion resistance as aluminum, it can only be vacuum-plated or painted, and the overall cost of stainless steel is more expensive than aluminum, of course, the quality is also a little higher.

Summary. Stainless steel door is a door made of stainless steel plate material, the same as the appearance of ordinary doors, the main material is stainless steel plate, and the filling inside is generally foam or honeycomb paper, which has a solid feeling when knocking; The middle is the door flower, the door flower is sandwiched between the inner and outer two layers of glass, so it can play the role of an anti-theft door, you can use the mold to make a variety of different door flowers, the most used in the residential area, generally used as the entrance door, to protect the inner door from being destroyed! The stainless steel plate door is formed by argon arc welding after direct cutting and bending of the stainless steel plate with a thickness of above, without a pipe skeleton, and the structure is compact and the effect is good, but because the cost is too high, few people do it.

Hello dear! We are glad and honored to answer your questions as follows; Stainless steel gate is good.

Hello dear! Relatively speaking, the stainless steel gate is good. Stainless steel door is good stainless steel from the perspective of corrosion resistance, of course, stainless steel is better, but the corrosion resistance of the door has no effect, high temperature, humidity, salt spray environment aluminum alloy can work stably for a long time, your home environment should not be so.

In terms of **, aluminum alloy is much cheaper than stainless steel. Another point, the aluminum alloy is light, and the door is opened and closed back and forth, which will be much more convenient if it is lighter.

The skeleton door was more fashionable before 2009, the frame was welded with a stainless steel rectangular pipe and then covered with a layer of stainless steel plate and the skeleton spot welded together, and the middle was generally hollowed out and equipped with decorative flowers, and then inlaid with double-sided glass, which was also more beautiful. Stainless steel doors are also divided into pure stainless steel plate doors and stainless steel skeleton doors. I hope mine can help you

**Different. Stainless steel is expensive, aluminum alloy is cheap; Take 304 stainless steel and 6061 aluminum alloy as an example. The volume must be expensive for stainless steel as the unit of calculation, and aluminum alloy must be expensive as the unit of mass.

The density of the two is very different, up to 3 times! Stainless steel plates, rods, and pipes are about 16 yuan kg on average, aluminum profiles are generally more than 30 yuan kg, and plates, rods, and pipes are about 20 yuan kg. The yield strength of stainless steel is twice as large as that of aluminum alloy, and the tensile strength is twice as large.

The melting point is twice as large, and the hardness is 3,4 times higher. The thermal and electrical conductivity is lower than that of aluminum alloy.

Titanium is an important structural metal developed in the 50s of the 20th century, and titanium alloy is widely used in various fields because of its high strength, good corrosion resistance and high heat resistance. Many countries in the world have recognized the importance of titanium alloy materials, and have successively researched and developed them, and have been put into practical application.

The first practical titanium alloy is the Ti-6Al-4V alloy successfully developed in the United States in 1954, because of its heat resistance, strength, plasticity, toughness, formability, weldability, corrosion resistance and biocompatibility are good, and become the ace alloy in the titanium alloy industry, the alloy has accounted for 75% 85% of all titanium alloys. Many other titanium alloys can be considered as modifications of the Ti-6Al-4V alloy.
