Brian Fasteners produces Aluminium 5086 Forgings in Houston for structural and heavy-duty marine applications. 5086 alloy is not heat-treatable with saltwater corrosion resistance as well as corrosion resistance in cryogenic temperatures. Our forgings are ASTM-compliant and go through machining and quality assurance. Employed in offshore and structural elements, they ensure corrosion and pressure durability.
Contains ~4.0–4.9% Mg, ~0.4–1.0% Mn; balance Al. Tensile ~275–350 MPa; yield ~215 MPa (H116). Non-heat-treatable; provides high fatigue and weld integrity. Outstanding marine corrosion resistance.

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.
Application in ship hull fittings, offshore platforms, cryogenic tanks, and reef foundations. Also applied to marine hardware and heavy machinery parts welded in heavy duty. Brian Fasteners supplies structural 5086 forgings constructed with the intent of endurance in harsh environmental conditions.
