A metal is a solid material which is typically hard, shiny, malleable, fusible and ductile. With good electrical and thermal conductivity.
Metals are mostly identified by the items made from them.
The types of materials include:
Shiny metals such as copper, silver and gold for decorative arts, jewelry and coins.
Iron and steel for structures like buildings, furniture and vehicle parts.
Copper for electric wires
Aluminium for cams, bottle tops and caps, household appliances and utensils, airplanes.
Bronze for church and school bells.
Physical properties of Ferrous and non-ferrous metals.
Ferrous Metals are metals that consists mostly of iron and small amount of other elements.
Some of the physical properties of ferrous metals include:
Magnetism
Ferrous metals are highly attracted to a magnet.
Heat Conductivity
ferrous metals are better conductors of heat than non-ferrous materials.
Appearance
Ferrous metals have a silvery colour
Electricity conductivity ferrous metals are poor conductors of electricity than non-ferrous metals.
Non-ferrous metals
These are metals that do not have any iron in them at all.
Some of the physical properties of non-ferrous materials include:
Magnetism- non-ferrous metals are not magnetic.
Heat conductivity- non-ferrous metals are poor conductors of heat than ferrous metals.
Appearance
Non-ferrous metals like gold have a more colourful appearance than ferrous metals.
Electricity conductivity- Non-ferrous metals like copper are better conductors of electricity than ferrous metals.
