Inconel 617 Alloy Coil (Ni-Cr-Co-Mo Alloy)
Engineered for aerospace, energy, and nuclear applications demanding extreme thermal stability and creep resistance, Inconel 617 alloy coil combines a nickel-chromium-cobalt-molybdenum matrix (Ni-52%, Cr-22%, Co-12.5%, Mo-9%) to deliver exceptional oxidation resistance, carburization resistance, and mechanical strength up to 1,100°C (2,012°F).
