The invention relates to a silver-based alloy material, which is prepared from 40-60 parts of silver, 20-30 parts of tungsten, 10-30 parts of nickel, 5-30 parts of copper, 5-30 parts of aluminum and 20-40 parts of titanium carbide. The silver-based alloy material has good electrical conductivity, heat-conducting property, low and stable contact resistance and high in resistance to electric loss, significantly improves the fusion welding resistance of electrical contact materials, and can be used for the high-capacity electrical contact materials.
