What metal is most commonly used in the household?

Copper is most often used in the household. Copper is second only to iron in its usefulness for centuries. Metal and its compounds are used in all spheres of life from electrical engineering to medicine and agriculture.

The electrical industry is the consumer of most of the world’s copper production. The metal is used in the manufacture of electrical devices such as cathodes and wires.

Copper compounds are most widely used in agriculture. Since their toxicity to certain insects, fungi and algae was discovered, these compounds have been used in insecticides, fungicides and to prevent algae from growing in drinking water tanks.
