Boikanyo Sheets and Plates, located in Cape Town, South Africa, is a reputable manufacturer and supplier of high-quality aluminium products, including Aluminium 5082 Circles. Renowned for their unwavering quality and precision, Boikanyo caters to a variety of sectors such as automotive, marine, engineering, and manufacturing. The company takes pride in offering products that adhere to rigorous local and international standards, ensuring features like corrosion resistance, strength, and excellent formability. Aluminium 5082 Circles from Boikanyo are perfect for deep drawing and forming tasks, making them a go-to choice for components that demand durability, lightweight design, and reliability in both structural and non-structural applications.
Aluminium 5082 Circles are crafted from an aluminium-magnesium alloy that contains about 4.0–4.9% magnesium and 0.2–0.8% manganese, along with trace amounts of chromium, iron, and silicon. This unique blend offers remarkable corrosion resistance, especially in marine and chemically aggressive environments. While the alloy isn’t heat-treatable, it does gain strength through cold working. Typically, the mechanical properties include a tensile strength ranging from 275–350 MPa and a yield strength of 125–200 MPa, with elongation between 10–20% depending on the temper. Aluminium 5082 maintains its mechanical properties even after forming and welding, making it ideal for applications that require both strength and flexibility.
