Properties of alloy X
Alloy X is a nickel-based superalloy known for its exceptional high-temperature strength, oxidation resistance, and fabricability. Alloy X was originally developed for use in gas turbine engine components but has found application in various industries due to its versatile properties. Alloy X is a valuable material in industries that require high-temperature strength, excellent oxidation resistance, and good fabricability. Its combination of properties makes it suitable for critical applications in aerospace, power generation, and heat treatment, among others. When welding Alloy X, CEWELD Alloy X is mostly used as filler metal. This welding wire is used for gas tungsten arc welding (GTAW/TIG) and gas metal arc welding (GMAW/MIG). CEWELD Alloy X is the matching wire for Alloy X and offers excellent corrosion resistance.
