Aluminium 1100 is a commercially pure grade that contains at least 99.0% aluminum, along with small amounts of copper (up to 0.05%), iron (up to 0.95%), silicon, zinc, and manganese. This alloy isn’t heat-treatable, but it boasts excellent corrosion resistance, thermal conductivity, and high ductility. Its tensile strength ranges from 90 to 150 MPa, yield strength from 30 to 95 MPa, and it can elongate up to 35%, depending on the temper. Aluminium 1100 is well-regarded for its ease of fabrication, weldability, and its ability to maintain mechanical integrity in low-stress situations.

Aluminum 1100 is unsuitable for high-temperature forging applications due to its low melting point and poor strength at elevated temperatures, making it better suited for cold working or low-temperature uses.
Aluminum 1100 offers excellent corrosion resistance, high ductility, good thermal conductivity, lightweight properties, and exceptional workability, making it ideal for custom forgings requiring precise shapes and resistance to harsh environments.
You’ll find Aluminium 1100 forgings in various industries that prioritize corrosion resistance, as well as electrical and thermal conductivity, and formability. In the electrical sector, it’s commonly used for bus bars, conductors, and electrical enclosures. The chemical and food processing industries rely on it for tanks, utensils, and storage equipment because of its non-reactive properties. In architecture and HVAC, it’s utilized in ductwork, roofing, and decorative trim. It’s also perfect for lightweight structural components, signage, and reflectors. Thanks to its excellent workability and resistance to environmental exposure, Aluminium 1100 is a fantastic choice for low-stress, high-performance applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
