Lock material introduction: What materials are locked?

When people buy locks, they are generally worried that the locks will not be durable or the surface will rust or oxidize. This problem is related to the materials used and surface treatment issues.


From a durable point of view, 1, the best material should be stainless steel, especially as a surface material, the more bright the use. It has good strength, strong corrosion resistance and constant color. However, there are many kinds of stainless steel, which can be mainly divided into ferrite and austenite. Ferritic stainless steel has magnetic properties, commonly known as stainless steel. It takes a long time, and the environment is not good, it will rust. Only austenitic stainless steel will not rust. The identification method is very simple. It can be identified with a magnet.


2, copper is one of the most widely used lock materials, its mechanical properties are good, corrosion resistance and processing performance are good, and the color is gorgeous, especially copper forged handles and other lock decorative parts, the surface is flat, the density is good, no Stomata, blisters. It is both strong and rust-proof. It can be used for plating various surface treatments such as 24K gold or gold, which is magnificent, noble and generous, adding a lot of color to people's home.


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


4, steel, good strength, low cost, but easy to rust, generally used as the internal structural material of the lock, not suitable for external decorative parts.


5, aluminum or aluminum alloy, ordinary aluminum alloy (except aerospace) is soft and light, the material strength is lower, but easy to form.
