Known to be the 8th most abundant metal, copper is highly malleable and ductile. It is a good conductor of electricity as well as heat. Copper is widely used as a conductor of electricity, plumbing, and construction industries. It is used to make electric cables and utensils. Copper alloys are combination of other metals like nickel, bronze and aluminum. One of the most important factor is that, copper can be 100% recycled. Scrap copper can be recycled again and again and the products made of copper can also be recycled over and over again. This makes copper the No.1 recyclable material.
