Product name
Copper and copper alloy silver-plated products

Category
Components and processing - Surface treatment

Overview
Provides silver plating services for various copper and copper alloy materials. The operation includes 3 fully automated production lines. Silver layer hardness reaches 110 Hv or above, with thickness ranging from 3 μm to 80 μm. Annual production area is approximately 5,000,000 square decimeters (~50,000 m²). The plated components are widely used in switchgear and electrical equipment across all voltage levels and for core moving-contact parts inside GIS, offering conductivity and wear resistance to ensure stable current transmission.

Applications

• Switchgear and electrical equipment across various voltage levels
• Core moving-contact components in Gas Insulated Switchgear (GIS)
