3003 Aluminium

3003 Aluminium is an alloy primarily composed of aluminium with manganese as its main alloying element, which gives it higher strength compared to the 1100 series. Known for its excellent corrosion resistance and workability, 3003 Aluminium is commonly used in applications requiring moderate strength and excellent formability. It is one of the most versatile and widely used aluminium alloys. Solitaire Steel & Engineering LLP, based in Khetwadi, Mumbai, India, specializes in the supply and export of high-quality 3003 Aluminium sheets, plates, tubes, pipes, bars, angles, channels, and fittings.
