Chirag Aluminium, a top-notch manufacturer and supplier located in Chennai, India, specializes in high-purity Aluminium 1100 Flanges. These flanges are perfect for applications that demand outstanding corrosion resistance, thermal conductivity, and formability. With their smooth finish and precise dimensions, our Aluminium 1100 Flanges find their way into various industries, including chemical processing, food and beverage, HVAC, and electrical systems. Crafted under rigorous quality standards, these flanges come in a range of sizes, pressure ratings, and custom configurations. At Chirag Aluminium, we’re dedicated to providing durable, reliable, and cost-effective aluminium flange solutions, all while ensuring timely service and a customer-focused approach.
Aluminium 1100 Flanges are made up of 99% pure aluminium, with trace amounts of copper (0.05–0.2%), iron, and silicon. This commercially pure alloy isn’t heat-treatable but boasts excellent corrosion resistance, particularly in chemical and marine settings. It has a tensile strength ranging from 90 to 130 MPa and a yield strength of about 35 MPa, along with impressive ductility and workability. While it may not be as strong as other aluminium grades, Aluminium 1100 is prized for its remarkable conductivity, weldability, and formability. It’s ideal for situations where mechanical loads are light, but corrosion resistance and thermal efficiency are crucial.

Aluminium 1100 Flanges are commonly used in low-pressure, non-critical applications where corrosion resistance and formability are essential. In the chemical and food processing sectors, they’re perfect for pipe connections, tanks, and fluid handling systems due to their non-reactive properties. In HVAC systems, you’ll find them in air duct flanges and fittings. The electrical industry also benefits from their high conductivity, making them great for grounding and bus connections. Additionally, these flanges are suitable for architectural trim, laboratory equipment, and pharmaceutical applications. Aluminium 1100 Flanges are the go-to choice when you need something lightweight, corrosion-resistant, and easy to fabricate.
