What are ASTM B241 Aluminium 5083 Fittings?
ASTM B241 Aluminium 5083 Fittings are piping components manufactured from Aluminium Alloy 5083, also known as ASTM B241 AlMg4.5Mn Fittings. This non-heat-treatable alloy belongs to the magnesium-aluminium alloy family and is well known for its outstanding corrosion resistance, especially in marine environments.
The alloy offers excellent weldability, high tensile strength, superior fatigue resistance, and good performance even at cryogenic temperatures. Because of these properties, EN AW-5083 aluminum fittings are commonly selected for marine vessels, offshore structures, LNG plants, chemical processing equipment, and transportation industries.
Our UNS A95083 pipe fittings comply with industry standards and are manufactured with precision to ensure leak-free and long-lasting piping systems.
