Hemi Metals, based in Hamilton, New Zealand, is a reputable manufacturer and supplier of Aluminium 5086 Forgings, celebrated for their remarkable corrosion resistance, high strength, and exceptional performance in both marine and structural applications. Utilizing cutting-edge forging techniques and rigorous metallurgical standards, Hemi Metals guarantees that each 5086 forging features consistent grain flow, improved toughness, and precise dimensional accuracy. Aluminium 5086 is highly sought after for its outstanding resistance to seawater, stress corrosion, and tough environmental conditions. Industries turn to Hemi Metals for reliable, high-strength Aluminium 5086 forgings that are perfect for challenging engineering, fabrication, and marine construction projects.
Aluminium 5086 Forgings consist of 3.5–4.5% magnesium and 0.20–0.40% manganese, along with trace amounts of chromium, which boost strength and corrosion resistance. This alloy boasts greater mechanical strength than 5052 while still offering excellent weldability and formability. Although it can’t be heat-treated, it responds well to strain hardening, enhancing its strength. In terms of mechanics, 5086 delivers impressive tensile strength, high fatigue resistance, and reliable performance even in low temperatures. Its corrosion resistance in seawater and marine environments makes it a top choice for marine and structural components.

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 find extensive use in marine, transportation, construction, and industrial sectors where high strength and corrosion resistance are crucial. Typical applications include boat hulls, ship structures, propeller parts, offshore platforms, pressure vessels, fuel tanks, and structural brackets. Its superb resistance to seawater makes it perfect for coastal infrastructure and underwater hardware. The alloy is also utilized in heavy-duty welded assemblies, military boat components, truck bodies, and load-bearing structural elements. Aluminium 5086 is highly valued for its durability and reliability in demanding environments.
