Anucha Metals is a top manufacturer and supplier of high-performance Aluminium 5086 Forgings in Bangkok, Thailand. Aluminium 5086 is well-known for its excellent corrosion resistance and strength, making it suitable for marine and structural applications in harsh environments. Our 5086 forgings are made using precise processes to ensure strong mechanical properties, stability, and weldability. We offer both custom and standard 5086 forgings for shipbuilding, pressure vessels, and transportation, meeting global industry standards. Our focus on quality and performance means we provide forgings that work reliably in seawater, chemicals, and high-stress conditions.
Aluminium 5086 contains about 93.5% aluminium, 4.0% magnesium, along with trace amounts of chromium, manganese, and iron. This non-heat-treatable alloy has a tensile strength of 275 to 350 MPa and yield strength up to 250 MPa, depending on the temper. It offers great corrosion resistance, especially in saltwater and marine environments.

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.
Aluminium 5086 Forgings are commonly used in marine engineering, including for ship hulls, decks, and superstructures, due to their resistance to saltwater corrosion. In transportation, they are used in truck trailers, rail cars, and fuel storage tanks. The alloy is also suitable for offshore platforms, pressure vessels, cryogenic tanks, and military equipment. With excellent welding and forming capabilities, 5086 forgings are favored for bridge structures, chemical storage units, and heavy-duty load-bearing parts. Their reliability under high stress and corrosive conditions makes them vital for coastal infrastructure and marine industrial components.
