Problems solved by technology

[0002] Silver-nickel alloy electrical contacts have the characteristics of good electrical conductivity and thermal conductivity, low and stable contact resistance, excellent processing performance, and strong resistance to electrical loss. However, the resistance to arc burning and welding resistance is restricted by the nickel content. As the content increases, the electrical properties decrease, and the welding resistance is worse than that of silver-metal oxide materials, so it has not been used as a large-capacity electrical contact material.
