Bimetallic Contacts for high-reliability switching devices
Bimetallic contacts are obtained by power metallurgy sintering. They combine good electrical conductivity (11 to 70% IACS) and excellent arc resistance, making them particularly suitable for applications where current interruption reach very high intensities. Typical bimetallic contacts include silver-copper (AgCu), silver-nickel (AgNi), tungsten copper (WCu), silver-palladium (AgPd), silver-carbon (AgC).
Ideal for medium and high voltage circuit breakers and contactors, as well as for direct current devices (railway traction, HVDC, high-power batteries), they support currents ranging from 100A to 100kA.
Their hardness, which can reach 200 HV, guarantees robustness and reliability even in the most critical conditions.
