Abstract
A contact conductor for electric vehicles is produced from an aluminum alloy containing an excess of silicon. The alloy comprises 0.1-1% by weight magnesium, 1-7% by weight silicon and the balance being aluminum and incidental impurities. The conductor is produced by the steps of: (1) casting the alloy into a continuous bar, (2) hot rolling to rod without intermediate cooling, (3) quenching the hot rolled rod, (4) cold deforming the quenched rod and (5) subjecting the cold deformed rod to artificial aging.
Claims6
A process for producing a contact conductor of improved physical strength from a wear-resistant aluminum alloy comprising 0.2-1% by weight magnesium, 1-7% by weight silicon and the balance being aluminum and incidental impurities,
- said process comprising the steps of:
- (1) casting said alloy into a continuous bar, (2) hot rolling to form rod without intermediate cooling, (3) quenching the hot rolled rod, (4) cold deforming the quenched rod and (5) subjecting the cold deformed rod to artificial aging.
