Because the price of brass keeps rising, zinc alloy plating technology has been rising too. At present, most of the lock cylinder have abandoned the use of brass to manufacture, instead of zinc alloy. This paper summarizes the main knowledge of zinc alloy.
Firstly, the characteristics of zinc alloys
1. The stability of melting requirement is not high. Melting at 385 C can be easily formed by die casting.
2. Strong mechanical properties and wear resistance at normal temperature.
3.gravity of material
4. The casting function is powerful. It can die-cast all kinds of precision and accurate devices with complex shape and thin wall according to different needs. The surface of the castings is smooth and layered.
5. There is no need to absorb iron in melting and die casting operation, and it is not easy to stick.
6. Easy surface treatment, such as electroplating, spraying, painting and other operations.
