From the heart of Hamilton, New Zealand, Kiri Aluminium takes pride in manufacturing and supplying industry-leading aluminium solutions, including their robust Aluminium 7075 Flat Bars. Forged with a commitment to local quality and global standards, Kiri delivers materials that are built to handle the most demanding challenges. Whether you are a local engineer or an international client, you can count on their expertise to provide the precise, high-performance flat bars your project requires, backed by a dedication to reliable service and customer success.
The exceptional strength of Aluminium 7075 Flat Bars comes from their unique composition. Primarily consisting of zinc as the major alloying element, along with magnesium and copper, this combination creates a material that rivals the strength of many types of steel. This results in flat bars that offer an outstanding strength-to-weight ratio, impressive toughness, and good resistance to fatigue. Despite their incredible durability, they retain the classic benefits of aluminium, including excellent machinability, allowing them to be precisely shaped for complex components.
