Hardware door locks material distinguish knowledge of stainless steel material superior

If the door lock is zinc alloy material, its hardness and anti-rust ability is very poor, is thick plating also easy to fade to black and rot foaming, but its advantages are easy to make complex patterns of parts, especially pressure casting. The more complex patterns that are seen in the market are likely to be made of zinc alloys, and consumers are carefully identified.

Steel, good strength, low cost, but easy to rust, generally used as a lock internal structure materials, unsuitable for exterior decoration.

Aluminium or aluminium alloys, ordinary aluminium alloys (except aerospace), soft and light, material strength at the bottom, but easy to process forming.

Copper is one of the most widely used locks materials, its mechanical properties, corrosion resistance and processing performance are good, and the color is gorgeous, especially copper forged handles and other locks decorative pieces, surface smoothness, density good, no pores, sand holes. Both firmly and anti-rust, can be used to plating gold or sand and other surface treatment, look magnificent, noble and generous, to people's home add a lot of color.

From a durable point of view, the best material should be stainless steel, especially as a surface material, the more bright it is. Its strength is good, the corrosion resistance is strong, the color does not change. But stainless steel also has a variety of, mainly can be divided into ferrite and austenite. Ferrite stainless steel Magnetic, commonly known as iron, long time, bad environment will rust, at present, only 304 stainless steel is the best stainless steel material.
