From the heart of Hamilton, New Zealand, Kiri Aluminium stands as a trusted manufacturer and supplier, deeply rooted in the local industry. We take pride in producing high-grade aluminium solutions that meet the rigorous demands of engineering and manufacturing. Our commitment to quality and reliability shines through in products like the Aluminium 7050 Round Bar, a premium alloy designed for those who cannot compromise on performance. We understand that behind every specification is a critical project, which is why we deliver materials you can count on.
The 7050 alloy is strengthened with zinc as its primary element, complemented by magnesium and copper, creating a remarkable combination of strength and toughness. This specific composition gives the round bar excellent resistance to stress corrosion cracking, a vital property for components under sustained pressure. It also maintains good machinability, allowing it to be precisely shaped for demanding applications. This balance of high strength and durability makes it a superior choice over many other aluminium grades for the most challenging environments.
