How does contact material selection impact relay lifespan?

How does contact material selection impact relay lifespan?

2025-12-17

Contact material determines arc resistance, electrical conductivity, and wear characteristics. In vacuum environments, improper material selection can lead to excessive erosion or unstable switching behavior, significantly shortening relay lifespan.


European and North American buyers frequently experience inconsistent relay performance caused by cost-driven material compromises. These issues typically emerge after prolonged use, making them difficult to trace back to the original sourcing decision.


Jingdezhen WPVAC Electric Co., Ltd. selects contact materials based on operating voltage, switching frequency, and load type. This application-oriented approach improves service life while maintaining cost efficiency for international customers.


Contact material is a technical decision that directly affects reliability and should never be treated as a generic specification.
