AgW High Current Silver Contact Tips For Circuit Breaker
Produce Name: Silver Contact Tips
Other name: Silver contact, AgW contacts, Silver tunsten contact, contact materials, break contact.
Materials introduce:
AgW50 has not only good conductivity of Ag, but also the great hardness, good arc erosion resistance, welding resistance, and low material transfer of W. The biggest characteristic of AgW is its high resistance against strong arc.
Besides the properties of AgW, AgWC has greater hardness, and is more superior under strong arc situation.
