Copper is a ductile and malleable base metal that is valued for its high thermal and electrical conductivity. Easily identifiable because of its iridescent, golden red color, copper and its alloys, have been used by humans for thousands of years.
Brass is mainly an alloy that consists of copper with zinc added. Brasses can have varying amounts of zinc or other elements added. These varying mixtures produce a wide range of properties and variation in color. Increased amounts of zinc provide the material with improved strength and ductility.
