In life, electric cabinet locks can often be seen, and its feature is to ensure the safety of funds, because the materials are different, and the application goals are not right. Therefore, the applied materials and the materials used on the surface are even more different. When you choose a lock, how can you understand it clearly?

First of all, let’s talk about materials. When you buy locks, in many cases, you will consider whether the locks are durable or whether the surface will rust or air oxidize after a period of time. From the perspective of use, the best material should be It is a stainless steel plate (stainless steel is divided into metallographic structure and martensite.), especially as a surface material, it becomes brighter and brighter. Its compressive strength is good, corrosion resistance is strong, and the color tone will not change. Ferritic stainless steel has magnetic, alias stainless steel. However, over time, if the natural environment is not very good, it will rust. In addition, one is low-alloy steel, and materials such as high-voltage cabinet locks are not easy to rust. The identification method is also very simple, try it with a magnet, the former one can be attracted, and the opposite is the latter one.

There is also a lock-making material that is copper, which is also one of the most common lock materials. , its physical properties are good, corrosion resistance and production characteristics are very good, and the color is bright, especially the copper forged door handle and its lock decorative design parts, the surface is flat, the relative density is good, no air holes, sand holes, both Sturdy and rust-resistant. In addition to the above two, there are also some lock materials that are not common, such as: zinc alloy materials, steel, aluminum or aluminum alloy profiles, these types have their own characteristics, and the details need to be looked at.

After talking about the lock application materials, let's talk about the surface treatment of the lock. Surface treatment refers to the use of metal material electro-deposition (alias electroplating process), spraying (called spray painting), organic chemical air oxidation (coloring) or other production and processing methods to cover or generate a protective film on the surface of the parts. The film plays a key role in anti-corrosion. At the same time, it also improves the appearance and durability of the product. It is an important factor to immediately consider the quality of the product. Thickness measurement in covering, adhesion inspection, corrosion resistance and wet and cold tests and appearance inspection These. For the accurate measurement of the coating of the door lock, various methods such as coating adhesion, strength, wet and cold test and appearance inspection should be carried out.
