2 Facts

2.1 Interesting Facts

Erbium metal is used as alloyed with Vanadium to make it softer.

Recent studies shows that it is helpful for metabolism.

Copper rarely found in its pure form in nature.

Copper Sulfate is mostly used in agricultural poison and as an algicide in water purification system.

3 Uses

3.1 Uses & Benefits

It has a tendency to get tarnished in the open air, but when alloyed with elements like erbium, vanadium, its hardness levels decreases.
Its compounds like Erbium oxide is used in safety glasses of welders and metal workers.

It is use for coinage and bullion.
Most of copper element is used in manufacturing electrical and electronic equipments such as wirings and components. It is also used in construction and industrial machine.
