Harsh Flanges, located in Mumbai, India, has built a solid reputation as a reliable manufacturer and supplier of high-performance Aluminium 5083 Flanges. These flanges are celebrated for their remarkable strength and resistance to corrosion, making them perfect for marine and industrial settings. Crafted from Aluminium 5083 alloy, they excel in tough conditions, including exposure to saltwater and chemical processes. Harsh Flanges guarantees that all products meet global standards like ASTM B209/B928 and ASME specifications. Our Aluminium 5083 flanges find extensive use in marine, oil & gas, transportation, and structural applications where lightweight and corrosion-resistant solutions are crucial.
Aluminium 5083 Flanges are mainly made up of Aluminium (~93%), along with Magnesium (4.0–4.9%), Manganese (0.4–1.0%), and small amounts of Chromium (0.05–0.25%). This unique blend provides excellent resistance to corrosion in both marine and chemically aggressive environments. The alloy boasts a tensile strength ranging from 275 to 350 MPa and a yield strength of about 125 to 200 MPa, along with good elongation and weldability. Even after welding, Aluminium 5083 maintains high strength and performs exceptionally well in cryogenic and high-stress situations. While it can’t be heat-treated, it can be work-hardened, making it perfect for pressure applications that demand lightweight and corrosion-resistant materials.
Harsh Flanges, a leading supplier in Mumbai, India, offers an extensive selection of Aluminium 5083 Flanges, including weld neck flanges, slip-on flanges, blind flanges, threaded flanges, and lap joint flanges. Designed for diverse industrial applications, our high-quality inventory and commitment to exceptional service make us a trusted choice for flange products in the region.
