Copper Variants Explained | HFA

Red copper, yellow copper, White copper, T1 copper… all just copper?

The term “red copper” is often used to indicate pure copper, of which T1 is the highest purity grade.

Red copper is copper without alloys, yellow copper is an alloy with zinc (brass), and white copper is an alloy with zinc and nickel. The purer it is, the softer and more malleable (easy to bend) it is.
