6101 (UNS A96101) is a heat-treatable aluminum alloy from the 6000 series, engineered to provide an excellent balance between high electrical conductivity and moderate mechanical strength. It is specifically designed for power transmission and electrical conduction components, such as bus bars, conductor strips, electrical connectors, and interconnections.
6101 aluminum sheet is a heat-treatable Al-Mg-Si alloy primarily designed for applications requiring a combination of high electrical conductivity and moderate mechanical strength. This alloy offers excellent machinability, good corrosion resistance, and superior finishing characteristics, making it an ideal choice for electrical and power transmission industries. 6101 aluminum provides about 55–60% IACS electrical conductivity, ensuring efficient current flow while maintaining structural integrity under mechanical stress.
It is commonly supplied in tempers such as T6, T61, and T65, which enhance its strength through artificial aging. The material can be easily fabricated by extrusion, rolling, or machining, and supports various surface finishes including anodizing, polishing, brushing, and coating. Standard specifications include ASTM B209 and ASME SB209, with typical thickness ranging from 0.2 mm to 50 mm, widths up to 1500 mm, and custom lengths available upon request.
Due to its excellent balance of conductivity, formability, and durability, 6101 aluminum sheet is widely used in bus bars, electrical connectors, heat exchangers, and other conductive components across power, automotive, and industrial sectors.
