1 1/2 inch Aluminum Hex Bar 6061-T6511 exhibits high strength, low weight, above average corrosion resistance, ease of machining, and has excellent weldability. The T6511 temper is stress relieved to ensure the material does not warp when machined. 6061 is the most commonly used aluminum alloy in the world due to its positive characteristics. It is typically used in aerospace, automotive, cameras, couplings, marine hardware, electrical components, decorative hardware, structural applications, pins, brakes, pistons, valves, and bicycle frames.
