Brian Fasteners, based in Houston, USA, produces Aluminium 1100 Flanges that are renowned for their fine corrosion resistance and formability. Being produced from commercially pure aluminium (99%+), these flanges are perfect for industries that demand high ductility and conductivity. Measured in exacting terms to ANSI/ASME standards with precise machining, Brian Fasteners assures uniform quality and traceability. With quick delivery and tailor-made sizes, their 1100 flanges are favored for food processing, chemical treatment, and electronics cooling systems. These flanges ensure consistent performance in non-pressurized and low to medium pressure applications where corrosion resistance is required and weldability is a key requirement.
Aluminium 1100 contains ~99% Al with small amounts of Fe, Si, and Cu. It shows tensile strength of ~110–160 MPa, yield strength of ~35–70 MPa, and elongation of more than 30%. The grade displays high thermal and electrical conductivity, high formability, and weldability. It is resistant to corrosion by fresh water and mild chemicals. Owing to low strength, it‘s appropriate for applications of low- to medium-pressure where corrosion resistance and ductility are needed more than mechanical loading.
Shawn Flanges, a leading supplier in Houston, USA, offers an extensive selection of Aluminium 1100 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.
