Our company relies on its own technical strength and technical team, the company established a research and development center, successfully developed silver tin oxide electrical contact materials. The material has good resistance to burning and welding resistance, by adding some additives to the powder metallurgy technology (vacuum sintering and extrusion) to produce AgSnO2 material, so that the contact resistance is low and the temperature rise is stable. AgSnO2 contact material is environmentally friendly and has excellent resistance to welding and arc ablation. Generally speaking, AgSn02 has better arc ablation resistance than AgCdO under the condition of large current. Under lamp or capacitive load, AgSnO2 shows stronger resistance to current impact than AgCdO and AgNi. Under AC resistive load, AgSn02 has slightly higher contact resistance than AgCd0, but under DC lamp or motor load, it shows low and stable contact resistance: under DC condition, compared with AgCdO, AgSnO2 has better material transfer performance. AgSnO2 contact materials are widely used in large capacity contactors, power relays, small and medium capacity low-voltage circuit breakers and automotive electrical appliances. The company currently produces AgSn02 contact material in the Sn02 content of 8% to 15%, the main production process includes internal oxidation process, powder oxidation process, powder metallurgy process and other material manufacturing process, the main form of supply is wire, sheet, rivets and welding components. Applications: Widely used in high-power relays, contactors, circuit breakers and switches, especially for T90. Relays, automotive relays.
