Copper
Copper is a soft, malleable and ductile metal with very high thermal and electrical conductivity. Cu has a red-orange metallic luster. Used as a conductor in electrical components, coins, jewellery, thermocouples in temperature measurements.
Aluminium
Aluminium is a soft, ductile and non- magnetic with a silver – white shine in appearance. Most widely used metal as it is used in car bodies,aerospace, mobile phones, computers. Al is one of the lightest metals but very strong, flexible and corrosion resistance due to thin layer of oxide film forming on the surface. Also a good conductor of electricity.
