Trends in the Improving Economic use of Aluminium

INDUSTRIAL usage of aluminium is increasing at a rate of about 10% every year . Whereas in 1958 the total world production of primary metal was rather less than 4 in short tons, in 1968 it is expected to be over 9 m tons.
The reasons leading to the initial usage of aluminium
for any given application are usually either technical or
strategic. Considerations of weight, durability, appearance
or conductivity may lead to the adoption of aluminium in preference to other materials or, alternatively, shortages of domestic supplies of other materials and of foreign exchange, may dictate the employment of locally produced aluminium.
