Some aspects of redesigning in aluminium

THE development of high strength aluminium alloys
has provided a great incentive to many manufacturers
to convert their products from other metals to alumi-nium.* In all such applications the specific mechan-
ical and physical properties of each structural mate-
rial have to be considered in the context of the
material and labour costs which directly govern the
efficiency and economy of a design : a third indirect
guiding factor being the cost of maintenance. One or
more of the following characteristics has or have in
many cases turned the decision in favour of using aluminium.
