Copper ball:

Copper balls have good electrical and thermal conductivity, strong ductility, and no impurities, making them suitable for electronic contacts, precision thermal conductivity, and food/medical scenarios.

Brass ball:

Brass balls have high hardness, wear and corrosion resistance, and are suitable for industrial transmission (such as bearings) and fluid control (such as valves), with excellent cost-effectiveness.

       The advantage of copper balls lies in their material properties and their outstanding performance in multiple dimensions. It has strong corrosion resistance and can adapt to multiple media such as water and salt spray; Moderate hardness, wear-resistant and compatible components; High processing accuracy, meeting precision requirements; It also has the characteristics of conductivity and non-magnetic, and is environmentally friendly and sustainable, which can solve the core needs of industry in a targeted manner.
