A well-known producer and supplier of Aluminium 2024 Circles, Kunj Sheets and Plates is based in Chennai, India, and serves businesses in need of high-strength, high-performance aluminium components. Kunj’s Aluminium 2024 Circles are well-known for their accuracy and quality, and are utilised extensively in the engineering, automotive, aerospace, and defence industries. These circles provide exceptional fatigue resistance and machinability because they are manufactured with state-of-the-art machinery and stringent quality controls. Kunj is a reputable supplier of aerospace-grade aluminium products because of their dedication to prompt delivery and customer satisfaction, which guarantees that every product satisfies particular customer needs as well as international standards.
With trace amounts of iron, silicon, and zinc, the primary constituents of Aluminium 2024 Circles are aluminium (90.7–94.7%), copper (3.8–4.9%), manganese (0.3–0.9%), and magnesium (1.2–1.8%). They are well-known for having high yield strength (~325 MPa) and tensile strength (up to 470 MPa), as well as good fatigue resistance and machinability. However, cladding or surface treatment frequently improves the moderate corrosion resistance. For improved performance, particularly in mechanical and aerospace applications requiring strength and dependability, this alloy is usually heat-treated to T4 or T6 conditions.
