Abstract

The invention discloses a high-conductivity copper-magnesium alloy material. The high-conductivity copper-magnesium alloy material comprises, by weight percentage, 0.05-0.15% of Mg, 0.005-0.01% of P, 0.01-0.15% of CuY15 alloy, 0.09-0.15% of Ge, 0.32-0.37% of Sc, smaller than or equal to 0.06% of the sum of other elements serving as impurities, and the balance Cu. The high-conductivity copper-magnesium alloy material reaches the level of a copper-based silver alloy in the aspects of appearance, conductivity, softening-resisting temperature and the like, is superior to the copper-based silver alloy in the aspects of strength and elongation and has the beneficial effect that the cost of raw materials is obviously reduced.

Description
