How to pick a good door lock?

The door lock is a zinc alloy material, its hardness and rust resistance is very poor, that is, thick plating is also easy to fade blackened and decayed foaming, but its advantage is that it is easy to make complex pattern parts, especially pressure casting. The more complex pattern locks seen in the market have a very large possibility that the zinc alloy is made of, consumers should carefully identify.


Steel, the strength is better, the cost is lower, but easy to rust, generally used as the internal structure of the lock material, not suitable for external decoration.

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

Copper is one of the more widely used locking materials, its mechanical properties are good, corrosion-resistant and processing performance is good, and colorful, especially copper forged handles and other locks decorative parts, surface flat, good density, no air holes, sand eye. Both strong and rust-proof, can be used to plate real gold or sand gold and other surface treatment, appear magnificent, noble and generous, to people's home to add a lot of color.

From a durable point of view, the better material should be stainless steel, especially as a surface material, the more bright. Its strength is good, corrosion resistance is strong, color unchanged. However, stainless steel also has a variety of, mainly can be divided into ferrite and Aolite. Ferritin stainless steel is magnetic, commonly known as rust-free iron, long time, the environment is not good will rust, at present, only 304 stainless steel is a better stainless steel material.
