NON – FERROUS
Non – ferrous metals generally include aluminum, copper, lead, zinc and tin, as well as precious metals like gold and silver. Their main advantage over ferrous materials is their malleability. They also have no iron content, giving them a higher resistance to rust and corrosion, and making them ideal for gutters, liquid pipes, roofing and outdoor signs. Lastly, they are non-magnetic, which is important for many electronic and wiring applications.
