Facts about Copper tell you about the atomic number 29 in the periodic system of element. It has the symbol Cu which stands for cuprum. It has reddish-orange color when you see the pure copper is exposed. Copper is ductile, malleable and soft. The thermal and electrical conductivity of copper is high. Here are some interesting facts about copper to note:

Facts about Copper 1: the main usage

In short, copper is mostly used for a constituent of numerous metal alloys, building material, electrical conductor and heat conductor.

Facts about Copper 2: the usage of copper for the first time

Human being used copper for the first time circa 8,000 BC. Circa 5,000 BC, human being began to smelt copper from the ore. In the nature, you can find copper in its pure form.

Facts about Copper 5: pigments

Copper was used as pigments in the past. The minerals like turquoise, malachite and azurite contain copper which have the green and blue tones.

Facts about Copper 6: the electrical conductivity

Do you know the electrical conductivity of copper? It is 59.6×106 S/m. It is considered high. It is partly because of the copper’s softness. If you compare the thermal conductivity of copper with other pure metals located at room temperature, it is second highest one. The first highest one is silver.
