Product Introduction
CoreMetal’s nickel alloy plates, sheets, and strips in Alloy 625 (UNS N06625), Alloy 219 (UNS N06619), and related grades provide exceptional strength and corrosion resistance for the most demanding applications. The niobium-molybdenum columbium composition in Alloy 625 provides excellent fatigue strength and thermal fatigue resistance, while maintaining oxidation resistance from cryogenic temperatures to 980°C. Available in various thicknesses from 0.64mm sheets to 102mm plates, these products serve aerospace, nuclear, marine, and chemical processing industries.
