The role of Aluminium and Aluminium alloys in Engineering Industries

IN speaking on the role of aluminium in the engineering
industries, where does one start ? What should one include and what should one omit? Truly it can be stated with confidence that aluminium is the metal of the twentieth century. The phenomenal growth of its popularity, shown by the figures of current and projected levels of production only hint in a cold statement of facts the extent of the penetration and impact that this metal has made on modern civilization.

a bus, train or tram, eat, drink or smoke, apply beauty
aids or take medicine, without coming within arms length of aluminium in some form or another.
