Aluminium 1100 is prized for its simplicity, being composed of at least 99% pure aluminium. This high purity gives it excellent corrosion resistance, particularly in various environments. While it’s not known for high strength, it offers good workability, making it easy to form and weld. This combination of properties makes it a very ductile and malleable material. It’s a great choice when ultimate strength is secondary to formability and resistance to rust.
Neesham Flanges, a leading supplier in Hamilton, New Zealand, offers an extensive selection of Aluminium 1100 Flanges, including weld neck flanges, slip-on flanges, blind flanges, threaded flanges, and lap joint flanges.

Aluminium 1100 flanges are extensively employed in those industries where high corrosion resistance, good thermal conductivity, and good workability are needed. They are used in typical applications such as chemical processing units, food and beverage manufacturing units, and marine fittings, where they are exposed to chemicals and moisture regularly.They are also used in HVAC systems, building structures, and electrical conductors due to their light weight and non-magnetic nature. In addition, Aluminium 1100 flanges are well suited for low-pressure piping as well as storage tanks. Their ease of fabrication and durability in harsh environments make them a reliable choice for many industrial and commercial applications.
