Aluminium 1100 flanges are made from 99% pure aluminium, which makes them one of the most corrosion-resistant and easily workable aluminium grades available. They boast excellent ductility, formability, and thermal and electrical conductivity, although they do have relatively lower strength compared to other aluminium alloys. The beauty of Aluminium 1100 is that it can be easily welded, brazed, or cold-formed without compromising its mechanical integrity. These characteristics make it perfect for applications that require superior corrosion resistance, lightweight construction, and a polished look. Ronwen Flanges guarantees consistent quality and precision in every Aluminium 1100 flange they manufacture.
