Most wire forms are made of a few types low carbon steels such as Industrial Quality (IQ) AISI 1008, Plating Quality (PQ) AISI 1018 and Cold Heading Quality (CHQ) AISI 1065. Each grade offers different mechanical properties like tensile strength, surface finish and malleability (ability to be cold worked or formed).
Mills ship plain or zinc coated pre-galvanized rod in coil form to produce wire. The basic material finish part can be used as is, painted, plastic coated for decorative appearance or electroplated for corrosion resistant decorative coating. Other alloys include stainless steels, copper, brass and aluminum would be used for electrical components, food processing components, medical instruments and severe and special duty components.
