    The addition of a small amount of silver to copper can significantly increase the softening temperature (recrystallization temperature) and creep strength, while the copper's electrical conductivity, thermal conductivity and plasticity are rarely reduced. The silver-copper used has not significant effect of age-hardening, and the cold hardening is generally used to increase the strength. It has good wear resistance, electrical contact and corrosion resistance. When it is made into tram lines, its service life is 2~4 times higher than that of ordinary hard copper.

    Used as heat-resistant, conductive equipment. Such as motor commutator pieces, generator rotor conductors, spot welding electrodes, communication lines, leads, wires, electron tube materials, etc.

    This is a copper alloy with a magnesium content of 0.7% to 0.85% Wmg. The trace Mg lowers the conductivity of copper, but it has a deoxidizing effect on copper and also improves the high temperature oxidation resistance of copper. In actual application of copper-magnesium alloys, the Mg content is generally less than 1% of Mg. If the Mg content is too high, the pressure processing performance deteriorates rapidly. Alloys of this type can only be worked hard and cannot be heat-treated
