Abstract Cu-12wt%Al alloy wires were prepared by vacuum melting and argon-shield vertical continuous unidirectional solidification (OCC) process. Effects of process parameters on the solidification forming were investigated; the microstructure and properties of the wires fabricated by OCC process were analyzed. The results showed that Cu-12wt%Al alloy wires, 6mm in diameter, with smooth surface and single crystal, can be continuously and stably fabricated under melting temperature 1250℃, drawing speed 9mm/min, cooling water volume 900L/h. The Cu-12wt%Al alloy wire with elongation 19.7%, Young’s modulus 167.9GPa and conductivity 22.23%IACS shows an excellent combination property.
