Silver Tungsten Carbide Grades
Silver tungsten carbide (Ag-WC) grades are usually designated based on the percentage of silver content by weight, and the corresponding balance of tungsten carbide. They are chosen based on the application's electrical, thermal, and mechanical requirements.
Typical Grades

Key Features & Applications |
AgWC50 |
Superior conductivity but lower hardness; used in low-current relays or precision switching components. |
AgWC40 |
Higher silver content improves conductivity; preferred for moderate-duty switching with frequent operation. |
AgWC30 |
Excellent overall performance with good conductivity and wear resistance; suitable for general-purpose relays and control contacts. |
