Standard Specification for Heat Resistant Aluminum-Zirconium Alloy Wire for Electrical Purposes
Show Complete Document History
The following bibliographic material is provided to assist you with your purchasing decision:
The specification covers heat resistant aluminum-zirconium alloy round wire for electrical purposes. There is a family of aluminum-zirconium alloys that are used for heat resistance, which differ by zirconium content, tensile strength, electrical conductivity, and maximum use temperature. The aluminum wire shall be made from drawing stock. The materials shall conform to the required mechanical properties such as tensile strength and elongation. Heat resistance, electrical resistivity, and diameter of the wire shall be measured. The density of aluminum-zirconium alloy shall be taken for the purpose of calculating mass, cross-section, and so forth. Wire shall be supplied in one continuous lengths of reel. coil, or spool. Joints may be made in the drawing stock or wire prior to final drawing by electrical-butt welding, cold-pressure welding, or by electric-butt, cold-upset welding.
1.1 This specification covers heat resistant aluminum-zirconium alloy round wire for electrical purposes. There is a family of aluminum-zirconium alloys that are used for heat-resistance (i.e. resist annealing), which differ by zirconium content, tensile strength, electrical conductivity, and maximum use temperature. This standard covers one currently commercially applicable alloy from this family.
1.2 The values stated in inch-pound units are standard. The SI equivalents of inch-pound units may be approximate.
