2020-5-19Answer i Duralumin, an alloy of aluminium, is used in the construction of aircraft because it is light, resistant to corrosion and has great tensile strength. ii The rusting of iron is a process of atmospheric corrosion, i.e., slow destruction of iron by moisture and atmospheric oxygen.

Another Reason Copper Is One of the Most Important

Copper is absorbed through the diet and is converted into usable form by combining with certain proteins to produce enzymes that assist in the function of many vital bodily processes. For industrial purposes, copper must be modified from its raw form in a refining process. Primary copper production starts with the extraction of copperbearing ...
