Some Important Properties of Metals
1.Why are metals of such importance for man’s life? The answer to this must be found in their characteristic properties. The most important of these is strength, which means that metals can withstand weight without bending and breaking. They are also corrosion-resistant and may assume different shapes, which distinguishes them from many other classes of materials. Some metals also have other special properties, two of which are conductivity and the property to be magnetized.
2.Strength is of great importance for most industrial purposes. That is why steel is widely used in modern industry. We know that steel constructions are used not only for building ships, planes and engines but also in building industry as well as for producing tubes, pipes, etc. For this purpose, engineers often use special kinds of steel.
3.As iron and steel are used more often than any other metal, we usually divide metallurgical materials into two classes: ferrous metals and non-ferrous ones.
4.We know that engineers use copper and aluminium for conducting electric current since these metals offer less resistance to it than ferrous metals do. A copper wire offers less resistance to current than an aluminium wire of the same size does. But due to its lighter weight aluminium offers less resistance per unit of weight
