Periodic Table Element Cu

The base element for this section is Copper.
We machine 8 versions of metals based on copper.
This is the oldest known metal on earth to be used as copper is natural element known as native copper required no refining to utilize. Copper in its near purer state oxidizes and grows a brown to black surface and over hundreds of years will grow a green patina.

We humans have a range of 1.4 to 2.1 milligrams of copper per 2.25 pounds of body mass, so this material is good for us.

Copper Group
