Non-ferrous metals and alloys are metallic mixtures that contain a base metal other than iron and one or more other elements. They are known for their resistance to corrosion, lightness, and non-magnetic qualities.  Here are some examples of non-ferrous metals and alloys: Copper: A non-ferrous metal that offers the best corrosion protection of the common sheath materials. Lead: A soft and malleable metal that has a low melting point and offers resistance against corrosion and the chemical environment. Lead is used in the construction of batteries and soldering. Nickel alloys: Non-ferrous... Show more
