Alloy 5083
Product catalog summary
Overview: This document provides technical specifications and typical properties for Alloy 5083 in various tempers, including 5083-0, 5083-H116, and 5083-H321. It includes chemical composition limits, physical properties, mechanical properties, and electrical properties.
Chemical Composition Limits: The document specifies the weight percentage limits for elements such as Copper (Cu), Magnesium (Mg), Manganese (Mn), Silicon (Si), Iron (Fe), Zinc (Zn), and Titanium (Ti). For example, Magnesium ranges from 4.00% to 4.90%, and Manganese is limited to 1.00%.
Typical Physical Properties: The average melting range is between 1095°F and 1180°F. The coefficient of thermal expansion is 13.2 (68-212°F per °F), and the thermal conductivity is approximately 810 in English units.
Typical US Mechanical Properties: The document lists tensile strength, yield strength, elongation, and hardness. For instance, the ultimate tensile strength is 42 KSI, and the yield strength is 21 KSI. Elongation is 22% in 2 inches, and the Brinell hardness number is 25.
Electrical Properties: Electrical conductivity at 682°F is 29 (equal volume) and 98 (equal weight), with resistivity at 36 ohm-cir. mil/foot.
Additional Notes: The document emphasizes that the typical properties are averages and not guaranteed. They are intended for comparison purposes and should not be used as engineering requirements or for design purposes.
