This 6061 aluminum angle measures 1/4 inch thick with 1-1/2 inch equal legs and is 8 feet long. It is made from 6061-T6 aluminum alloy with a standard mill finish. 6061-T6 is a versatile and strong aluminum alloy known for its excellent strength-to-weight ratio, good corrosion resistance, and machinability. This heavier-duty equal-leg angle is commonly used in structural applications, fabrication shops, maintenance departments, and industrial projects where a robust L-shaped aluminum angle is required for frames, supports, brackets, base plates, or custom components.
