Door lock knowledge: Zinc alloy materials have poor hardness and rust resistance, that is, thick plating is easy to fade and blacken and rot and blister, but the advantage is that it is easy to make parts with complicated patterns, 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. 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. Aluminum or aluminum alloy, ordinary aluminum alloy (except aerospace) is soft and light, and the material strength is lower, but it is easy to form. Copper is one of the most widely used lock materials. It has good mechanical properties, good corrosion resistance and processing properties, and its color is beautiful. Especially for copper forged handles and other locks, the surface is flat, the density is good, and there is no air hole. Sand eyes. It is both strong and rust-proof. It can be used for various surface treatments such as gold or gold. It looks magnificent, noble and generous, adding a lot of color to people's home. From a durable point of view, the best material should be stainless steel, especially as a surface material, the more bright it is. 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 can rust if the environment is not good. At present, only 304 stainless steel is the best stainless steel material.
