加拿大的加工能力(与原铝生产量相比)较小。1967年轧制品11万8千吨,挤压制品4万5千吨,铸件2万7千吨,其他9千吨,共计19万9千吨,1968年达到21万吨。除了从炼铝到加工连续生产的阿尔康公司之外,有20家公司从事轧制品,挤压品,电线及铸件等生产,多数是国外投资。特别是,四家轧制公司中三家是英国雷诺金属公司投资,而挤压加工公司属于美国的雷诺、凯萨及阿马科斯公司。1.阿尔康铝业公司
Canada’s processing capacity (compared with primary aluminum production) is small. In 1967 there were 118,000 tons of rolled products, 45,000 tons of extruded products, 27,000 tons of castings, and 9,000 tons of other materials, amounting to 190,900 tons in 1968 and 210,000 tons in 1968. Apart from Alcon, which produces aluminum continuously through processing, 20 companies are engaged in the production of rolled products, extruded products, wires and castings, mostly foreign investments. In particular, three of the four rolling companies are invested by the British company Renault, while the extrusion companies belong to the United States, Renault, Caesar and Amax.
