1100 Aluminium

1100 Aluminium is a commercially pure aluminium alloy, composed of 99.0% aluminium. It offers excellent corrosion resistance, high thermal and electrical conductivity, and superior workability. Known for its malleability, it is commonly used in industries that require deep drawing, spinning, welding, or bending. Due to its relatively low strength, 1100 aluminium is primarily used in applications where strength is not a priority. Solitaire Steel & Engineering LLP, based in Khetwadi, Mumbai, India, provides high-quality 1100 aluminium products including sheets, plates, tubes, pipes, bars, angles, channels, and fittings, ensuring high precision and compliance with global standards.
