Renowned for their outstanding service, consistent quality, and precise manufacturing, Boikanyo caters to a wide range of industries with customized aluminium solutions. With a strong emphasis on durability, corrosion resistance, and performance, all Aluminium 5086 Circles are crafted to meet rigorous industry standards. Whether they’re used in marine, transport, or structural applications, Boikanyo Sheets and Plates offers aluminium products that blend strength, functionality, and efficiency to fulfill specific customer needs across South Africa and beyond.
Aluminium 5086 Circles are primarily composed of aluminium (about 95.4%) alloyed with magnesium (3.5–4.5%), along with trace amounts of iron, silicon, manganese, and chromium. This unique blend provides remarkable corrosion resistance, particularly in saltwater environments. The alloy boasts moderate to high strength, with a tensile strength ranging from 240–330 MPa and a yield strength of about 125–280 MPa, depending on temper conditions like H32 or H116. Aluminium 5086 also features good weldability and maintains its strength after welding. Its non-heat-treatable nature makes it ideal for cold working, and it performs admirably under stress and fatigue in challenging environments.

Aluminium 5086 circles offer high-quality corrosion resistance, mainly in marine environments, because of their excessive magnesium content material. They show off sturdy electricity and sturdiness, making them appropriate for traumatic applications within the aerospace, defense, and transportation industries. The cloth is likewise lightweight, ensuring power performance in applications like structural components. Aluminium 5086 is distinctly formable, bearing in mind clean machining and shaping into circles for numerous uses. Its resistance to strain corrosion cracking and potential to face up to harsh climate situations make it ideal for out of doors and business programs.
Aluminium 5086 Circles are extensively utilized in marine and coastal applications due to their exceptional resistance to saltwater corrosion. They’re commonly found in boat hulls, shipbuilding components, and offshore platforms. In the transportation sector, they’re used for truck trailers, railway cars, and fuel tanks, thanks to their impressive strength-to-weight ratio and durability. Structural applications include storage tanks, pressure vessels, and welded structures that demand resilience and longevity.
