When people choose locks, they generally worry that they will not be durable or that the surface will rust or oxidize shortly after use. This issue is related to the materials used and surface treatment.
From a durable perspective, the best material should be stainless steel, especially when used as a surface material, the more it is used, the brighter it becomes. It has good strength, strong corrosion resistance, and unchanged color.
Copper is one of the most widely used lock materials, with good mechanical properties, corrosion resistance and processing performance, and bright colors. Especially for copper forged handles and other lock decorative parts, the surface is flat, the density is good, and there are no pores or sand holes. It is both sturdy and rust proof, and can be used for various surface treatments such as 24K gold plating or sand gold plating, appearing magnificent, noble and generous, adding a lot of color to people's homes.
Zinc alloy materials have much lower strength and rust resistance, but their advantage is that they are easy to make parts with complex patterns, especially in pressure casting. The more complex patterns of locks seen on the market are likely made of zinc alloy, and consumers should carefully identify them.
Steel has good strength and low cost, but is prone to rusting. It is generally used as an internal structural material for door locks and is not suitable for external decoration.
Aluminum or aluminum alloy, ordinary aluminum alloy (excluding aerospace) is soft and lightweight, with lower material strength, but easy to process and shape.
