Aluminium metal is used in making aluminium foils by hammering them.
Mercury is silvery white and it is the only metal that is liquid at room temperature and it is used in thermometers because it expands on heating.
Copper is used in making electric wires because they are good conductor of heat and electricity and they are highly malleable and ductile.
Graphite is used for making pencil lead because it is extremely brittle and it is an excellent tool for writing without the application of a large amount of stress.
