摘　　要：以15%Mg的铜镁合金为原料,在真空感应炉中用不同压强制备1%Mg的铜镁合金,研究了压强对铜镁合金镁成分的影响。结果表明,铜镁合金制备中镁元素易烧损,在较低压强下能降低镁元素的烧损。压强在1 000 Pa时,镁含量可以控制在0.76%,烧损率为24%。The 1% Mg copper-magnesium alloy was prepared with 15% Mg copper-magnesium alloy as raw material at different pressures in a vacuum induction furnace. The results show that the burning loss of magnesium in the preparation of copper-magnesium alloy is easy, and the burning loss of magnesium can be reduced at lower pressure. When the pressure is 1 000 Pa, the magnesium content can be controlled at 0.76% and the burning loss rate is 24%.
