Silver Tungsten Carbide Sheet

The silver tungsten carbide sheet is a planar composite material produced via powder metallurgy, composed primarily of tungsten carbide (WC) for hardness and wear resistance, and silver (Ag) for electrical and thermal conductivity. It is specially designed for applications requiring a flat, wear-resistant, and conductive surface, such as electrical contacts, arc-resistant plates, switchgear components, and thermal dissipation panels.
This material exhibits outstanding arc erosion resistance, thermal stability, and uniform electrical conductivity across its surface, making it ideal for applications where surface uniformity, contact reliability, and structural integrity are critical.
Application Areas:
1.High-voltage switchgear contacts and arc plates
2.Vacuum relays, electrical contact modules
3.Welding equipment heat spreaders or base contacts
4.Anti-wear faceplates, conductive sliding interfaces, replaceable terminal modules
5.Special-purpose electrodes, thermal control layers, aerospace/defense electric-resistant components
