What Are The Raw Materials Of The Key Lock

  When you buy a key lock, you are generally worried that the key lock will rust or oxidize after not being used for a long time. This problem is related to the data used and the appearance processing problem.

  From the point of view of durability, 1. The best material should be stainless steel, especially stainless steel lock is used as the surface material, the more it is used, the brighter it is. It has good strength, strong corrosion resistance, and constant color. But there are also many kinds of stainless steel, which can be mainly divided into ferrite and austenite. Ferritic stainless steel is magnetic, commonly known as stainless steel, it will rust even if the environment is not good for a long time, only austenitic stainless steel will not rust, the identification method is very simple, you can identify it with a magnet.

  2. Copper is one of the most widely used key lock materials. It has good mechanical properties, good corrosion resistance, and processing performance, and has a beautiful color, especially for copper forged handles and other key lock decorative parts, with a smooth appearance and good density. , No porosity, trachoma. It is strong and anti-rust and can be used for various surface treatments such as 24K gold or placer gold. It looks resplendent, noble, and generous, and adds a lot of color to everyone's home.

  3. Zinc alloy material, its strength and rust resistance are much worse, but its advantage is that it is easy to make parts with complex patterns, especially for pressure forging. The key locks with messy patterns seen in the market are likely to be made of zinc alloy, and consumers should be careful to distinguish them.

  4. Steel has good strength and low cost, but it is easy to rust. It is usually used as the internal structural material of the key lock and is not suitable for external decoration.

  5. Aluminum or aluminum alloy, general aluminum alloy (except for aerospace) is soft and light, and the material strength is relatively low, but it is easy to process and form.
