Aluminium 1100 Flanges

Aluminium Alloy 1100 Flanges are high-grade flanges made using the purest form of aluminium. They have excellent corrosion resistance and are highly malleable, making them perfect for various applications. The alloy composition consists of iron (Fe) content not exceeding 0.35%, silicon (Si) content not exceeding 0.50%, copper (Cu) content not exceeding 0.10%, zinc (Zn) content not exceeding 0.10%, magnesium (Mg )content between 0.45% and 0.90% by weight, manganese (Mn) Content up to 1% by weight, titanium(Ti), vanadium(V), chromium(Cr), nickel(Ni), lead(Pb ), tin(Sn ), bismuth(Bi ) etc as impurities in trace amounts below specified limits and rest is aluminium in percentage above 99%.


Aluminium Alloy 1100 Flanges are widely used in many industries, such as aircraft, marine, and construction. Their properties make them ideal for various applications due to their strength-to-weight ratio, high corrosion resistance, excellent electrical conductivity, good formability and weldability. These flanges are also widely known for having low water absorption, which helps prevent corrosion and rusting in humid environments. Additionally, they have great thermal stability, which gives them an added advantage in some production processes that experience extreme temperatures.
