A rotor conductor of a squirrel-cage induction motor is made of an aluminum-base alloy consisting essentially of 0.3 to 4% by weight of manganese, 0.15 to 0.9% by weight of chromium, 0.05 to 0.6% by weight of titanium, 0.01 to 0.12% by weight of boron, not more than 0.3% by weight of iron and not more than 0.3% by weight of silicon, the balance being aluminum, said squirrel-cage rotor generating a large starting torque.
