Semih Metals, located in Istanbul, Turkey, is a reliable manufacturer and supplier of Aluminium 5086 Forgings. They provide top-notch aluminum alloy products that are crafted for outstanding corrosion resistance, strength, and formability. With a focus on precision and rigorous quality control, these forgings deliver excellent dimensional accuracy, a smooth surface finish, and dependable mechanical performance. Semih Metals guarantees that their Aluminium 5086 Forgings meet the high standards required by industries like marine, automotive, aerospace, and chemical processing, where lightweight, durable, and corrosion-resistant materials are crucial.
Aluminium 5086 Forgings mainly consist of aluminum (around 95%), magnesium (approximately 4–4.9%), and trace amounts of manganese (about 0.2–0.5%). This composition gives them remarkable resistance to corrosion in seawater and environments rich in chlorides. On the mechanical side, 5086 boasts good tensile strength, ductility, fatigue resistance, and workability, making it perfect for forming, bending, and welding tasks. Its blend of mechanical strength and corrosion resistance ensures reliable performance in both structural and industrial settings.

Aluminum 5086 is not ideal for high-temperature forging applications due to its relatively low melting point and limited strength at elevated temperatures. It is better suited for marine and structural applications.
Aluminum 5086 offers high strength, excellent corrosion resistance, and weldability. It is ideal for marine environments, aerospace applications, and custom forgings requiring durability, lightweight properties, and easy fabrication.
Aluminum 5086's excellent workability enables easy forging, allowing it to maintain strength and formability. However, its susceptibility to cold working requires careful temperature control during forging to prevent cracking.
These forgings are widely utilized in sectors that demand lightweight, robust, and corrosion-resistant materials. You’ll find them in shipbuilding, marine structures, fuel tanks, pressure vessels, automotive parts, and chemical processing equipment. They also play a role in aerospace structures, architectural frameworks, and transportation systems where durability, strength, and resistance to tough conditions are vital. Thanks to their impressive corrosion resistance, mechanical performance, and versatility, Aluminium 5086 Forgings offer long-lasting reliability in challenging industrial, marine, and structural applications.
