Boikanyo Sheets and Plates stands out as a reliable manufacturer and supplier of top-notch aluminium products, proudly catering to a diverse array of industries from its home base in Cape Town, South Africa. Among its specialized offerings, Aluminium 2024 Circles are particularly esteemed for their remarkable strength, fatigue resistance, and aerospace-grade performance. Designed to thrive in demanding conditions, these circles are crafted to exacting standards, ensuring both reliability and structural integrity. With a strong emphasis on quality, consistency, and customer satisfaction, Boikanyo is a dependable partner for clients in search of high-performance aluminium solutions tailored to their specific needs and operational challenges.
Aluminium 2024 Circles are primarily made up of aluminium (about 90.7%) mixed with copper (3.8–4.9%), manganese (0.3–0.9%), and magnesium (1.2–1.8%). This heat-treatable alloy is celebrated for its impressive strength-to-weight ratio and fatigue resistance. It boasts a tensile strength ranging from approximately 400–530 MPa and a yield strength of 270–480 MPa, depending on the temper (like T3 or T351). While Aluminium 2024 isn’t as corrosion-resistant as some other alloys, it can be safeguarded with coatings or cladding. Its exceptional mechanical properties make it perfect for applications where high strength and load-bearing capacity are crucial.
