Where are aluminum alloys generally used?

Aluminum alloy is mostly used in places that require light weight and good corrosion resistance in the atmosphere, machinery, metallurgy, chemical industry, electrical appliances, railways and other industries, and the largest amount is used in the aerospace industry for aircraft structural materials and civil aluminum alloy doors and windows. To put it simply, a light steel keel.

It is made of iron, and the aluminum alloy keel is made of aluminum, and the light steel keel is generally U or C-type, and the aluminum alloy keel is mostly T-shaped. But there is a kind of lacquered keel made of iron sheets. It is also a T-type.

But it's relatively soft. The light steel keel is generally used in the dark frame, that is, the keel seal gypsum board is used as a coating, and the aluminum alloy is more in the open frame, and the paint keel has aluminum plates and mineral wool boards.

The cost of aluminum alloy keel is high, that is, the expensive light steel keel** is relatively cheap First of all, almost all use light steel keel, light steel keel is a load-bearing keel, the general model is du50, du38, du60 aluminum alloy keel is just with 60 * 60 calcium silicate plate.

With it, it is divided into large and small T and corners. The light steel keel is gypsum board; Calcium silicate board; Cement pressure plates.

and other ceiling materials. Light steel keels are generally produced and processed in accordance with national standards. Ordinary ones are flat ceilings. It can also be made of ordinary shapes, and the aluminum keel of the ceiling is usually made of aluminum alloy ceiling.

The matching aluminum alloy keel that I used at the time of day. The keels and panels of this series are formatted products for ceilings. Some simple shapes can also be made on some ceilings, such as the shape of the ceiling in the form of arches, etc.

The floor spring is actually a hydraulic door closer, which allows the door to close automatically after opening, which is very convenient. As an aluminum alloy fitting, we must do an inspection after installing the floor spring, pay attention to the hydraulic part can not leak, and the speed of opening and closing is normal. Handle:

The handle is a very common aluminum alloy die-casting, which is mostly used in windows and doors.

Above. Relatively speaking, it has strong wear resistance and anti-corrosion, and has strong decorative properties.

The shuttle's crew compartment, forward fuselage, middle fuselage, rear fuselage, vertical tail, flaps, lifting ailerons, and horizontal tail are all made of aluminum alloy. The main structural material of various artificial earth satellites and space probes is also aluminum alloy. Iron (should be steel) has a wide range of applications, can involve all industries, even the plastic industry must use machines made of steel materials, it can be said that there is no iron in the world dare not imagine, so all countries in the world are vigorously developing their own steel industry.

Stainless steel is a class of steel, belongs to special performance steel, where corrosion resistance is needed, the chemical industry and the shipbuilding industry is the largest industry, the production of sulfuric acid, nitric acid, hydrochloric acid, fertilizer, etc. Distinction: Aluminum alloy is very light, can be easily distinguished, stainless steel does not rust, is white, but heavier, and general steel although heavier, but easy to rust, usually black and not slippery, so it is called ferrous metal.

All kinds of aircraft use aluminum alloy as the main structural material. Skins, beams, ribs, stringers, bulkheads, and landing gear on aircraft can all be made of aluminum alloy. The amount of aluminum used in airplanes varies depending on the application.

Civil aircraft focusing on economic benefits are widely used because of the cheap aluminum alloy, such as the aluminum alloy used in the Boeing 767 passenger aircraft, which accounts for about 81% of the weight of the fuselage structure. Military aircraft require good combat performance and relatively reduce the amount of aluminum, such as the maximum flight speed of the F-15 high-performance fighter with Mach number only uses aluminum alloy. Some aluminum alloys have good low-temperature properties, are not cold and brittle under -183 to 253 [2oC], can work in liquid hydrogen and liquid oxygen environments, it does not react chemically with concentrated nitric acid and metamethylhydrazine, and has good welding properties, so it is a good material for manufacturing liquid rockets.

The fuel tanks, oxidizer tanks, inter-tank segments, inter-stage segments, tail segments and instrument compartments of the Saturn-5 launch vehicle launched the Apollo spacecraft are all made of aluminum alloy.

Aluminum alloys are alloys of aluminum and copper, silicon, magnesium, zinc, and manganese.

The main alloying elements of aluminum alloy are copper, silicon, magnesium, zinc and manganese; Minor alloying elements are nickel, iron, titanium, chromium, lithium, etc. Aluminum alloy has low density, but relatively high strength, close to or more than high-quality steel, good plasticity, can be processed into various profiles, has excellent electrical conductivity, thermal conductivity and corrosion resistance, is widely used in industry, and the amount of use is second only to steel.

Physical properties of aluminum alloys

1. Low density.

The density of aluminum alloys is close, about 1 3 of iron or copper.

2. High strength.

Aluminum alloy has high strength, and the strength of the matrix can be strengthened by a certain degree of cold working, and some grades of aluminum alloy can also be strengthened by heat treatment.

3. Good electrical and thermal conductivity.

The electrical and thermal conductivity of aluminum alloys is second only to silver, copper and gold.

4. Good corrosion resistance.

The surface of aluminum is easy to naturally produce a dense and firm Al2O3 protective film, which can well protect the substrate from corrosion. Through artificial anodizing and coloring, cast aluminum alloys with good casting properties or deformed aluminum alloys with good plasticity can be obtained.

Introduction to aluminum alloys.

Aluminum alloy is an alloy based on aluminum with a certain amount of other alloying elements, which belongs to one of the light metal materials. In addition to the characteristics of aluminum, aluminum alloys will also contain some alloy properties due to the different types and quantities of alloying elements added to the ruler. The strength of aluminum is close to that of high-alloy steel, but the stiffness exceeds that of steel, and it has good castability and plastic processability, as well as good electrical and thermal conductivity.
