1050 aluminum coils are commercial pure aluminum extrusions in the 1000 series. According to the international alloy nomenclature, the last two digits of the 1050 aluminum coil “50” means that the aluminum content must be above 99.50%. Only when this condition is met can the product be qualified. At the same time, the 1050 aluminum coil is also a non-heat-treated aluminum alloy with low strength, so the 1050 aluminum coil cannot be strengthened by heat treatment.
