Silver Tungsten Carbide Properties

Silver tungsten carbide (AgWC) is a composite material that offers an excellent combination of electrical and mechanical properties. Its key performance characteristics include:

1. Electrical Properties
High Electrical Conductivity: Thanks to the silver content, AgWC provides efficient current flow.
Low Contact Resistance: Minimal resistance at the contact point reduces energy loss and improves conductivity.
Low Material Transfer Rate: Excellent stability under high switching frequency and arc conditions.

2. Arc Resistance
Excellent Arc Erosion Resistance: Tungsten carbide delivers superior resistance to arc wear.
Strong Anti-Welding Performance: Prevents sticking or welding under high-temperature, high-current arcs.
Extended Service Life: Superior arc and sticking resistance ensure a longer operational lifespan compared to conventional silver-based materials.

3. Mechanical Properties
High Hardness and Strength: The WC matrix gives the material exceptional compressive strength and wear resistance.
Dense and Uniform Structure: Achieved through vacuum infiltration, offering excellent mechanical reliability.

4. Thermal Properties
Outstanding Thermal Stability: Maintains structural and functional integrity even under elevated temperatures.
Good Thermal Conductivity: Enhances heat dissipation, reducing localized heating and its impact on electrical performance.
