6061 Aluminum Alloy
6061 aluminum alloy is a heat-treatable material offering medium-to-high strength, excellent corrosion resistance, and exceptional weldability — making it one of the most widely used aluminum alloys across industries. Stronger than 6005A and more formable than 7075, it strikes a balance between performance and processability.
Well-suited for structural components, 6061 is a popular choice in aerospace, automotive, and high-performance sporting applications. While its strength slightly decreases in welded areas, its overall fatigue resistance and machinability make it a highly reliable, multi-purpose material.
