Conductivity (Figs 4 and 5)
Thermal conductivity and electrical conductivity are the measures of ability of a material to conduct heat and
electricity. Conductivity will vary from metal to metal. Copper and aluminium are good conductors of heat and
electricity.
Magnetic property
A metal is said to possess a magnetic property if it is attracted by a magnet.
Almost all ferrous metals, except some types of stainless steel, can be attracted by a magnet, and all non-ferrous
metals and their alloys are not attracted by a magnet.
