Kiri Aluminium, a reputable manufacturer and supplier located in Hamilton, New Zealand, specializes in high-strength Aluminium 2024 Flat Bars designed for tough aerospace, mechanical, and structural applications. These flat bars are crafted using cutting-edge extrusion and heat-treatment techniques, resulting in outstanding tensile strength, excellent machinability, and reliable fatigue resistance. Known for its impressive strength-to-weight ratio, Aluminium 2024 makes these bars perfect for precision-engineered and high-load components. Kiri Aluminium offers Aluminium 2024 Flat Bars in various sizes and tempers to cater to the needs of aircraft structures, defense systems, automotive parts, industrial machinery, and custom-fabricated components, ensuring durability, accuracy, and long-lasting performance.
Aluminium 2024 Flat Bars are made from a heat-treatable aluminium-copper alloy that contains approximately 3.8–4.9% copper, along with magnesium, manganese, silicon, iron, and trace elements. This alloy provides exceptional tensile and yield strength, excellent machinability, and robust fatigue resistance after heat treatment. It retains hardness and dimensional stability under load, making it ideal for precision structural components. While its corrosion resistance is moderate, anodizing or protective coatings can significantly boost durability. Overall, Aluminium 2024 boasts a strong mechanical profile that is perfect for strength-critical engineering applications.
