Kiri Aluminium is a trusted name in Hamilton, New Zealand, proudly manufacturing and supplying high-quality aluminium solutions to a diverse range of industries. Our focus is on delivering exceptional materials like Aluminium 5083 Circles, combining local expertise with a commitment to robust performance and reliability. We understand that our customers need more than just a product; they need a partner who ensures their projects are built on a foundation of superior strength and durability, which is exactly what we provide from our base in the heart of the Waikato.
At the heart of these circles is the renowned 5083 alloy, celebrated for its exceptional resistance to salt water and corrosion, making it a standout marine-grade material. Its composition, primarily aluminium with significant additions of magnesium, gives it a superb strength-to-weight ratio. This alloy is not heat-treatable but gains its impressive mechanical properties through strain hardening, resulting in a material that is both strong and remarkably workable, holding up beautifully under demanding conditions.
