Brian Fasteners, Houston, USA, produces Nimonic 80A bars and rods through precision vacuum melting, hot working, and ageing processes. It is a nickel superalloy with high-temperature strength and oxidation properties. Every bar undergoes stringent dimensional and material quality testing. For aerospace, power generation, and automotive turbocharger markets, Brian Fasteners offers custom lengths, quick delivery, and technical expertise. Being a reliable supplier, the company offers consistent performance of Nimonic 80A bars and rods in critical hot-section applications in American industry sectors.
Nimonic 80A contains about 60% Ni, 20% Cr, 10% Co, 1–2% Al and Ti, and <0.1% carbon. Aged, tensile strength is 900–1,400 MPa, yield strength 600–1,000 MPa, and elongation 15–25%. The alloy has creep resistance and structural integrity up to 700 °C. Oxidation resistance is provided by chromium and aluminum content and precipitated gamma-prime provides high-temperature strength.

Yes, Nimonic 80A, a nickel-based alloy, can be susceptible to galvanic corrosion when in contact with materials that have significantly different electrochemical potentials, especially in the presence of an electrolyte.
Yes, Nimonic 80A bar can be welded. It is commonly welded using techniques like TIG or MIG welding, with preheating and post-weld heat treatment to prevent cracking.
Nimonic 80A bars are available in various sizes, typically from 6mm to 250mm in diameter, and lengths up to 6 meters. Common finishes include bright, polished, and cold-drawn.
Brian Fasteners‘ Nimonic 80A rods and bars find applications in turbine discs, blades, and combustion liners in aerospace and power generation industries. They are applied to turbocharger rotors and shafts in motor vehicle applications. Industrial process furnaces utilize them as high-temperature fixtures and fasteners. Their high mechanical strength and oxidation resistance qualify them for parts subjected to extreme thermal stress. Brian Fasteners supplies Nimonic 80A bars specifically designed for high-performance hot-section components in crucial engineering systems.
