Also referred to as "red metals", both brass and copper are electrically and thermally conductive. BRASS An alloy of copper and zinc, brasses are, in general, more malleable and machinable than either copper or zinc, but cannot be heat treated

COPPER The base for all “red metals," copper is corrosion- resistant and can be easily soldered and brazed. It also has the best thermal and electrical conductivity of any of the red metals.
