| 摘 要： | To promote the solution of chromium in copper and the purity of copper-chromium （Cu-Cr） alloy, vacuum continuous casting （VCC） process was employed to fabricate the Cu-Cr alloy required for electrode material. Cu-0.6Cr （containing 0.6%（mass fraction） chromium） alloy bar with a diameter of 12 mm was cast with a constant rate of 250 mm/min. The microstructure, mechanical properties, and physical properties were discussed. After solid solution strengthening and aging treatments, Cu-0.6Cr alloy fabricated by VCC process has higher tensile strength （σ≥314 MPa）, elongation rate （δ≥34%）, conductivity （≥80.5% IACS）, and hardness （80 HRB） compared to the as-cast alloy.
