Nowadays, people usually use stainless steel as the material for making bag locks. Bag locks made of stainless steel have a bright surface, high strength, and are resistant to corrosion and discoloration. By means of sandblasting, brushing, polishing, machining and other methods, stainless steel can also be used in various forms such as glossy, matt surface and hemp surface. It is beautiful and practical.

Because copper has strong corrosion resistance, mechanical properties and processing properties are very good, therefore, the application in the manufacture of bag locks is also more extensive, especially some relatively high-end bag locks, generally adopt 24K gold or gold plating process locks Surface treatment, so that luggage locks as a whole looks magnificent, noble and generous. Copper forged bag locks have a smooth surface, high density, no holes, no blisters, and are both solid and rust-proof.

Zinc alloy materials have low cost and are suitable for pressure casting. They are also unique in the manufacture of bag locks. The luggage locks cast out of zinc alloy materials have characteristics such as low melting temperature and many air holes, which are not conducive to coating, but can be made into various complicated patterns. The bag locks with complicated designs on the market are mostly made of zinc alloys. of.

In addition, in the internal structure of the bag lock, steel materials are used more. In order to improve the durability and aesthetics of the bag lock, the surface of the luggage lock is generally treated. For example, electroplating, painting, chemical oxidation, etc. are used to cover or form a protective film on the surface of the bag lock part to prevent corrosion. Anti-corrosion, but also increase the beauty and durability of bag locks, improve the life of bag locks.
