Refractory Contact Materials and Applications

Refractory contact materials such as silver tungsten and copper tungsten are engineered for arc resistance and durability in high-duty electrical switching environments. These systems are optimized to withstand elevated temperatures and high-energy switching cycles while maintaining interface stability and predictable electrical performance.

As a leading U.S. manufacturer of refractory electrical contact materials, Checon supports demanding applications including industrial circuit protection, automatic transfer switching, and grid power distribution. These environments require the strength, arc tolerance, and heat resistance delivered by refractory systems such as silver tungsten, silver tungsten carbide, and silver graphite.
