When the user purchases the lock, he or she will be worried that the lock is not durable or susceptible to rust or oxidation. This problem is related to the materials used for the door lock and the surface treatment problems. Door lock materials are stainless steel, copper, zinc alloy, aluminum alloy, iron and so on. What kind of material is good, Xiao Bian to everyone to analyze the three materials.
From a durable point of view, the best material should be stainless steel door locks, especially with surface materials, the more light the more. Its strength is good. Strong corrosion resistance, long lasting color resistance. It should be noted that there are many types of stainless steel, which can be divided into ferrite and austenite. Two different stainless steel materials, the performance is not the same, the price is not the same. Only austenitic stainless steel will not rust, how to identify, you can use a magnet to test it.
Divided from the use of universality, copper door locks are veritable. Copper door locks have good mechanical properties, good wear resistance and processing performance, plus bright colors, especially copper forged handles and other lock decorative parts, the surface is smooth, non-porous, good density, trachoma. Both strong and rust-proof, can be used to plate 24K gold or gold and other surface treatment, it looks noble and generous, magnificent, to add a lot of color to people's homes.
From the point of view of manufacturability, its strength and rust resistance are inferior to stainless steel and copper door locks. However, due to its low strength, zinc alloys can easily be made into more complex pattern door locks, especially pressure casting. Styles are varied and diverse.
