For welders, fabricators, machinists, and serious DIYers, this USAMILY aluminum angle is a versatile and high-quality material to have in your shop. It's made from 6061-T6511 aluminum alloy, which is one of the most common and useful grades. The 'T6' temper means it's solution heat-treated and artificially aged, giving it good strength and excellent machining characteristics. This specific piece is an angle (L-shaped) with equal legs: each leg is 3 inches wide, the thickness is a substantial 1/4 inch (6mm), and it comes in a 12-inch length. The finish is a standard mill finish – it's clean and ready for you to cut, drill, weld, or machine for your project. 6061 aluminum is known for being relatively lightweight, having good corrosion resistance, and being easily weldable. It's used in everything from custom furniture frames and workshop carts to automotive parts, marine hardware, and structural frameworks. If you need a strong, workable aluminum angle for a fabrication project, this is a reliable piece of mill stock from a trusted supplier.
