Kiri Aluminium, a reputable manufacturer and supplier located in Hamilton, New Zealand, specializes in high-strength Aluminium 2024 Circles designed for tough aerospace, structural, and precision-machining tasks. These circles are crafted using cutting-edge rolling, stamping, and heat-treatment techniques, ensuring they provide outstanding tensile strength, excellent fatigue resistance, and dependable dimensional stability even under heavy loads. Known for its superb machinability and impressive strength-to-weight ratio, Aluminium 2024 is perfect for high-performance engineering components. Kiri Aluminium offers these circles in a variety of diameters and tempers, catering to needs in aircraft parts, defense systems, automotive engineering, industrial tooling, and custom-machined assemblies, all while maintaining consistent quality and durability.
Aluminium 2024 Circles are composed of a heat-treatable aluminium-copper alloy that contains about 3.8–4.9% copper, along with magnesium, manganese, silicon, iron, and trace elements. This unique blend results in exceptional tensile and yield strength, robust fatigue resistance, and remarkable machinability post-heat treatment. The alloy retains its rigidity and dimensional accuracy under stress, making it ideal for critical structural and machined components. While its natural corrosion resistance is moderate, applying anodising or protective coatings significantly boosts its durability. In summary, Aluminium 2024 combines strength, hardness, and machining efficiency in a powerful way.
