Common non-ferrous metals are aluminum (or aluminum), copper, lead, nickel, tin, zinc, brass, and precious metals. The main characteristic is that non-ferrous metals are non-magnetic, light, strong, and durable. Because of their lightweight and durability, non-ferrous metals get used in the airline industry, for instance.
