GH3128 High-Temperature Alloy is a nickel-based superalloy specially designed for aerospace, power generation, and high-temperature industrial applications. It offers excellent oxidation resistance, superior thermal stability, and remarkable mechanical strength, making it ideal for components such as turbine blades, combustion chambers, and heat exchangers operating under extreme thermal environments.
Product Overview
GH3128 is a nickel-based high-temperature alloy that is strengthened by tungsten and molybdenum in solid solution, along with boron, cerium, and zirconium to enhance grain boundary strength. The alloy features high plasticity, excellent long-term creep resistance, and good oxidation resistance. It also exhibits excellent processing properties, such as stamping and welding. GH3128 offers superior overall performance compared to similar nickel-based solid-solution alloys (such as GH3044 and GH3536), making it especially well-suited for long-term operation in high-temperature environments. The alloy is commonly used for manufacturing key components in aerospace engine combustion chambers, afterburners, and other high-temperature parts.
