6061 aluminum sheet is a high-quality alloy product produced by heat treatment and pre-stretching. Although its strength cannot be compared with 2000 series alloy or 7000 alloy series, the composition of 6061 aluminum alloy is mainly Mg and Si, so 6061 aluminum sheet exhibits excellent processing performance, excellent weldability and electroplating, good corrosion resistance, high toughness and other characteristics. It is worth mentioning that the dense structure of 6061 aluminum sheet does not deform after processing. In addition, 6061 aluminum alloy can be easily polished, colored film, etc., and its oxidation effect is excellent. Knowing this, it is not difficult to find that 6061 aluminum sheet is a suitable material for the manufacture of precision machinery, automotive wheels, 3C products, mobile phone shells, molds, trolley cases, alloy doors and windows.
