They are used to make pans, since they are good conductors of heat. They are used in electrical cables, because they are malleable, ductile and good conductors of electricity. They are strong so used to build scaffolding and bridges. They make a ringing sound, sonorous, hence their use in bell making. Non-metalsUsed as insulating material around wire cables since they do not conduct electricity. Used to make pan handles as they are poor conductors of heat.
