            Aluminum profiles with precise temper control When aluminum parts fail in strength or deform too easily, it’s often not the alloy but the temper designation that was overlooked. Aluminum alloy temper designations describe how the material was mechanically or thermally treated, directly affecting its strength, ductility, and corrosion resistance.
