Kiri Aluminium, a well-respected manufacturer and supplier located in Hamilton, New Zealand, specializes in high-strength Aluminium 2024 Bars designed for tough aerospace, mechanical, and structural applications. These bars are crafted using cutting-edge extrusion and heat-treatment techniques, resulting in outstanding tensile strength, impressive fatigue resistance, and excellent machinability. Aluminium 2024 is highly regarded for its strength-to-weight ratio, making it perfect for precision-engineered and high-load components. Kiri Aluminium offers Aluminium 2024 Bars in a variety of diameters and tempers, catering to needs in aircraft parts, defense systems, heavy machinery, automotive structures, and industrial fabrication. With a commitment to strict quality standards and a customer-first approach, the company guarantees durable, dimensionally accurate bars for applications where strength is critical.
Aluminium 2024 Bars are made from 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 very high tensile and yield strength, robust fatigue resistance, and excellent machinability post-heat treatment. The alloy boasts good hardness and structural stability under load, making it a top choice for critical mechanical applications. While its natural resistance to corrosion is moderate, anodizing or applying protective coatings can significantly enhance its durability. In summary, Aluminium 2024 strikes a remarkable balance between strength, toughness, and machining performance that’s friendly to precision work.
