6061-T6 Aluminum flat bar or “flat stock” is an excellent candidate for most processing techniques and both interior and exterior applications. Aluminum flat bars have defined edges, a smooth finish, and are light weight. Common applications include shelves, brackets, sculptures, and structural trim. With above average corrosion resistance, this is an excellent choice wherever strength is required.
Most commonly used. High strength & good welding. Not good formability - If formed, needs a very gradual radius.
