Co!!er can be re!laced *ith Aluinu as it is also goodconductor o" electricity( lighter and chea!er than
co!!er.
4ubber can be re!laced *ith thero!lastic elastoersas they are easily elted and extruded.
5teel can be re!laced by >ber rein"orced !olyers( theygive ore ductility( strength and is lighter than steel.
