Steel, good strength, low cost, but easy to rust, generally used as the internal structural material of the lock, not suitable for external decorative parts.
Aluminum or aluminum alloy, ordinary aluminum alloy (except aerospace) is soft and light, and the material strength is lower, but it is easy to form.
Copper is one of the most widely used lock materials. It has good mechanical properties, good corrosion resistance and processing properties, and its color is beautiful.
