China Metal Parts Surface Treatment
Metal Parts Surface Treatment is a process of finishing the surface of a material to improve its cosmetic, functional, or durability properties. Many types of surface treatment processes are used in industry, and even more combinations of processes. Common processes include electroplating, plating, anodizing, painting, powder coating, and galvanizing.
What are the common materials and applications of china metal parts？
Here are some common materials used for metal parts in China:
Aluminum alloys: Al-Mg alloy, Al-Zn alloy, Al-Li alloy, and so on.
Brass: Cu-Zn alloy, Cu-Sn alloy, Cu-Pb alloy, and so on.
Bronze: Cu-Sn alloy, Cu-Zn alloy, and so on.
Copper alloys: Cu-Ni alloy and so on.
Steel: C-Mn, C-Mn-Si, and so on.
Stainless steel: 304, 316L, and so on.
What is the tolerance of China metal parts manufacturing?
The tolerance of China metal parts manufacturing is 0.05mm. The tolerance can be customized according to different customers’ requirements.
Tolerance is a deviation in size or shape from the nominal size, which is standard in the industry. For example, if the diameter of a hole is specified at 1mm and its actual dimension is 0.955mm, then it has a tolerance of 0.045mm. If the tolerance is too high, it will cause problems such as excessive friction during assembly and poor accuracy. If the tolerance is too high, it will cause problems such as excessive friction during assembly and poor accuracy. The tolerance should be determined based on the application requirements of each component and component assembly process requirements.
