What material is good for door locks? What material is good to buy for door locks

Each material has its own different properties, there is no best attribute, only the most suitable door lock, the choice of door lock needs to be selected according to their actual needs.

<> let's take a look at the characteristics of different material door locks:

1. Space aluminum - easy to process and form; Low development costs; The texture is soft and easy to deform; Low strength and poor impact resistance; The color is cold and hard and monotonous, easy to oxidize, and has a short life; The style is monotonous and simple, the material itself is of low value, and the fire protection function is poor.

2. Stainless steel - strong corrosion resistance, high strength, fireproof, drill-proof, anti-prying, anti-sawing, anti-impact, long service life; The texture is uniform, the density is good, there are no pores, sand holes, and the color is bright and uniform, delicate and delicate; Green and environmentally friendly, the production process is complex, and the development cost is high.

3. Zinc alloy - easy to cast and process, low development cost; There are many styles and surface colors; Low strength, poor impact resistance, poor rust resistance, the internal material is prone to oxidation and spots; Brittle, loose and easy to break, not anti-drilling, anti-prying, anti-sawing; The material itself is inexpensive; Not resistant to low temperatures; Poor fire protection.

Now it is very dangerous for a house to have no locks, so locks are indispensable hardware accessories in modern families, especially indoor door locks, which can not only be used to decorate, but also to protect the safety of the family.

Now there are many indoor door lock materials, including iron, pure copper, zinc alloy, aluminum-magnesium alloy, stainless steel and so on. If you want to say what material is good for indoor door locks now, if you have enough budget, it is best to choose stainless steel indoor door locks. Stainless steel locks have high strength, strong corrosion resistance, and do not change color, making them the best choice for indoor door locks.

Because zinc alloy interior door locks are very similar to stainless steel locks, you should be careful not to be fooled by the boss when you go to a lock store to buy locks. If you want to buy a good interior door lock, it is very important to master the following five points of knowledge.

1. Pay attention to lock materials.

When buying an indoor door lock, you must pay attention to the material of the lock. Earlier we said that stainless steel locks are the best, in addition to stainless steel locks, copper locks and zinc alloy locks are also a good choice, copper locks have superior mechanical properties, but ** is also relatively high; The zinc alloy lock is strong and wear-resistant, and has strong corrosion resistance.

2. Observe the treatment quality of the surface of the lock.

Observing the quality of the surface treatment of the lock is also the key to measuring a good lock. At present, there are three main types of surface treatment of locks on the market, namely coloring, painting and electroplating, which are all in order to add a dense protective film on the surface of the lock, in addition to the role of anti-corrosion and anti-rust, but also to make the lock more beautiful. These three treatment methods are undoubtedly the best electroplating, the plating is smooth and uniform, the color is bright, there are no bubbles, and the anti-corrosion and anti-rust ability is first-class.

3. Check the lock implementation standards.

The locks are implemented standards, and some foreign locks are implemented by QB standards, and the quality of the locks is also higher, so imported locks are generally more expensive. Now some brands of locks in China have been implementing the QB standard, and only some small manufacturers are still implementing the original GB standard, so you must see the implementation standard of the lock when you buy.

4. You can feel the quality of the lock.

In addition to observation, we can also feel the quality of the lock. Generally speaking, the heavier the lock, the thicker the material used on the surface, the more resistant to wear and tear, and the higher the quality will be. On the contrary, the lighter the lock, the weaker the material, the lower the quality, and easy to damage.

5. Check whether the lock cylinder spring of the lock is sensitive.

You can open the lock cylinder repeatedly to see the sensitivity of the lock cylinder spring, if it is not very sensitive, do not buy it.

Among them, the electronic IC card door lock is not suitable for home use, because from the function of anti-theft and anti-prying, the electronic lock is not stronger than the mechanical lock, but it is much more expensive, so it is mainly suitable for hotels, restaurants and other places. Anti-theft and fireproof door locks are used for anti-theft doors and entrance doors in the living room, and most of them are currently using a three-way insurance structure, that is, 3 deadbolts lock the handle and the upper and lower latches respectively. When choosing, pay attention to the material of the lock and the test certificate of the relevant department.

The handle door locks on the market are rich in colors, including gold-plated, titanium-plated, silver-plated, chrome-plated, as well as imitation wood grain, frosted, imitation bronze, imitation gemstone color. No matter the color, the surface is required to be delicate and smooth, without spots and without rust. With the refinement and in-depth development of home decoration and decoration, the application of locks is also more specific, such as sliding door locks used on sliding doors, glass locks used on glass doors, special bumper locks for children's rooms, etc., but the wide range of applications is still handle door locks.

There are two types of handle door locks: ball locks and handle locks. There is a stainless steel bathroom ball lock with a waterproof function that is specially designed for toilets. Once in the bathroom, press the safety button on the handle on the side of the room and the door will be locked.

The most important thing is the quality of the lock. When you choose a lock, try to buy products with higher brand awareness, because there is a problem of mutual opening rate. The mutual opening rate refers to the ratio of the lock and the key to each other, the less the lock is opened by a key, the stronger the safety and reliability of the lock.

At present, the mutual opening rate of the world's well-known brand locks is only 1 in 10,000, and the mutual opening rate of excellent domestic lock brands is also about 1 in 6,000, while some informal, no production strength of the lock factory produces products with a mutual opening rate of 1/30, such a lock, the safety and reliability are too poor. A good brand product, although the ** is slightly higher, but the quality of the lock is guaranteed, and it is still worth it. If you still want to choose the best product, then you can try to choose a lock with a large number of key teeth, because the more teeth of the key, the greater the difference, and the lower the mutual opening rate of the lock.

From the point of view of the durability of the lock, the best material should be stainless steel, especially when used as a surface material, the more you use it, the brighter it becomes. It has good strength, strong corrosion resistance and unchanged color. But there are also many kinds of stainless steels, which can be mainly divided into ferrite and austenite.

Ferritic stainless steel is magnetic, commonly known as stainless iron, long time, bad environment will also rust, only austenitic stainless steel will not rust, the identification method is very simple, with a magnet to try to identify. Copper locks are one of the most widely used lock materials, with good mechanical properties, good corrosion resistance and processing performance, and bright color, especially copper forged lock handles and other lock decorations, with smooth surface, good density, no porosity and sand holes. It is both strong and rust-proof, and can be used to plate 24k gold or placer gold and other surface treatments, and the copper locks appear magnificent, noble and generous, adding a lot of color to people's homes.

Zinc alloy material locks, its strength and anti-rust ability are much worse, but its advantage is that it is easy to make complex pattern parts, especially pressure casting. The more complex patterns of locks seen on the market are very likely to be made of zinc alloy, and consumers should carefully identify them.

When buying door locks, different materials, quality and service life are also different. What material is good to buy for the door lock? PChouse will take you to find out.

1. The main added elements of zinc alloy are aluminum, copper, magnesium, etc., zinc alloy can be divided into two categories according to the processing technology: deformation and casting, and the fluidity and corrosion resistance of cast zinc alloy are good. Cast zinc alloy is usually used in the panel and handle of door locks, and Torch brand zinc alloy is a national quality inspection-free material.

2. Fully imported electrolytic plate, the advantage is strong fingerprint resistance and rust resistance, but the cost is relatively high. It is suitable for the use of lock body housing.

3. Brass, usually classified by copper content, H59 1 copper rod has considerable toughness, suitable for lock cylinder production, and H62 copper plate with higher copper content is used for key manufacturing.

4. Cupronickel has excellent mechanical and physical properties, and has the advantages of strong ductility, beautiful color and corrosion resistance. The main element added to cupronickel is nickel, and the master spoon such as high-grade angle spoons and double-row bead spoons are usually made of cupronickel.

1.Zinc alloy material.

Easy casting processing, medium production cost, multiple styles, multiple surface treatment colors, general compressive strength, medium impact resistance, general corrosion resistance, easy to model, and can be designed with a variety of appearance materials. It is used more in the mid-to-high-end door lock market.

2.Space aluminum.

Easy to process and form, low production cost, soft texture, relative deformation, low compressive strength, medium impact resistance, cold and hard color, monotonous, easy air nurture, short life, monotonous simple model, low cost of its own value, poor fire resistance.

3.Stainless steel.

4.Strong corrosion resistance, high compressive strength, fireproof, drill-proof, anti-fluffing, anti-sawing, anti-impact, long service life, uniform texture, high density, no holes, blisters, bright and uniform color, delicate, green and environmentally friendly, complex production process, high production cost.

Usually the more common door lock material is mainly stainless steel, the hardness is enough, anti-theft and anti-picking, and the security can also be guaranteed to a certain extent.
