We supply core components for high-voltage DC relays and contactors used in electric vehicles, including riveted contact assemblies, moving and stationary contacts, moving and stationary iron cores, Kovar frame plates, and magnetic plates. Our broader EV portfolio also includes battery terminals, cup seals, gaskets, copper washers, and custom-stamped parts. We can tailor materials, dimensions, and configurations to specific application requirements.

We offer electrical-grade silver powders in micron and submicron grades, ultrafine functional silver powders, and silver-coated composite powders. We supply these products for applications including electrical contact materials, electronic pastes, photovoltaics, 5G communications, electroplating, chemical processing, and other industrial uses. We also provide precious-metal recovery and refining services for industrial and electronic scrap.

Yes. We offer cadmium-free options including AgSnO₂, AgSnO₂In₂O₃, AgZnO, and AgCuO. For certain lower-current applications, we may also recommend AgNi. AgSnO₂ is a common alternative to AgCdO because of its resistance to contact welding and arc erosion. Because no material is a universal drop-in replacement, we recommend validating the selected formulation and contact design under actual operating conditions.

Yes. We can reduce precious metal use through material formulation and structural optimization. At the material level, we can optimize silver content, functional-phase proportions, and additive systems to balance conductivity, resistance to contact welding and arc erosion, and electrical life. Structural options include bimetal or trimetal rivets, clad or inlaid strips, T-shaped composite profile strips, and optimized silver-layer thickness and placement.

Yes. We can reduce contact volume through contact geometry and manufacturing-process optimization while maintaining the required current-carrying and switching performance. Each design is assessed for temperature rise, mechanical strength, breaking capacity, and electrical life before production. The achievable reduction depends on the device design, electrical load, and space constraints.
