Abstract：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%.
