Copper is a ductile and malleable base metal that is valued for its high thermal and electrical conductivity.
•Bronze: 88-95% Cu by weight. Used in coins, cymbals, and artwork.
•Aluminum Bronze: 74-95% Cu by weight. Higher corrosion resistance than regular bronze and used for marine applications.
•Brass: a wide range of alloys containing 50-90% Cu by weight. Made into everything from ammunition cartridges to doorknobs.
•Cupronickel: 55-90% Cu by weight. Used in coins, marine applications and in musical instrument strings.
