Busbars for aluminum alloy material, as well as laser welding body of the bus bar and the other member using the aluminum alloy material

摘要

PROBLEM TO BE SOLVED: To provide an aluminum alloy material for a bus bar having excellent strength, conductivity and laser weldability and to provide a laser welded product of a bus bar using the same and other members.SOLUTION: There is provided an aluminum alloy material for a bus bar which contains 0.70 to 2.50 mass% of Fe and is composed of residual Al and inevitable impurities, wherein the aluminum alloy has an electric conductivity of 55.0% IACS or more and 14000 pieces/mmor more of Al-Fe based intermetallic compounds having a circle-equivalent diameter of 1 to 3 μm exist in the metal texture. There is also provided a laser welded product of a bus bar using the same and other members.
