How to identify the hardware lock material

If the door lock is made of zinc alloy material, its hardness and anti-rust ability are poor, that is, thick plating is also easy to fade, blacken, and rot and blistering, but its advantage is that it is easy to make complicated pattern parts, especially pressure casting. The more complex pattern locks seen on the market are likely to be made of zinc alloys, and consumers should carefully identify them. Iron and Steel, better strength, lower cost, but easy to rust, generally used as internal structural materials for locks, not suitable for external trim. Aluminum or aluminum alloys, common aluminum alloys (except for aerospace) are soft and lightweight, and have a lower material strength, but are easier to shape and shape. Copper is one of the most widely used lock materials. Its mechanical properties are good, corrosion resistance and processing performance are good, and bright color, especially copper forged handles and other lock decorative parts, the surface is flat, high density, no pores, Blisters. Both solid and rust-proof, can be used to plate gold or gold and other surface treatment, it looks magnificent, noble and generous, adding a lot of color to people's homes. From a durable point of view, the best material should be stainless steel, especially as a surface material, the more bright and bright. Its strength, corrosion resistance, color unchanged. However, there are many types of stainless steel, which can be mainly divided into ferrite and austenite. Ferritic stainless steel is magnetic, commonly known as stainless steel, long time, the environment will not be rusty, at present, only 304 stainless steel is the best stainless steel material.
