Aluminium 1100 flanges are crafted from commercially pure aluminium, celebrated for their impressive corrosion resistance, high thermal and electrical conductivity, and remarkable formability. These flanges are lightweight and easy to machine, ensuring dependable performance in low- to moderate-pressure piping systems. With a smooth surface finish and good weldability, Aluminium 1100 flanges are perfect for applications where cleanliness, ease of installation, and corrosion protection are key. Their non-magnetic and non-toxic properties make them even more suitable for specialized industrial settings.
Aluminium 1100 consists of at least 99.0% aluminium, along with small amounts of copper, iron, silicon, manganese, zinc, and other elements. This unique blend gives it excellent resistance to both atmospheric and chemical corrosion, as well as outstanding conductivity. On the mechanical side, Aluminium 1100 flanges have low tensile and yield strength but boast high ductility and elongation, allowing them to endure forming and machining without cracking. They shine in non-load-bearing and low-stress applications.
