Explain properties and application of Aluminium.
Properties of Aluminium:
1) Pure aluminium in colour is silver white.
2) Aluminium is a ductile metal and can be put to a shape by drawing, forging and rolling.
3) Aluminium melts at 6550C.
4) Aluminium is resistant to corrosion.
5) Its tensile strength is 60MN/m2.
6) Aluminium can be alloyed with the other elements.
7) Annealing can soften Aluminium.
8) Aluminium has a higher thermal conductivity.
Applications of Aluminium:
It is widely used as conductor for power transmission and distribution. Aluminium is used busbars, in overhead transmission lines and ACSR conductors.
