Metals for high-temperature applications

Your Trusted Source for High Temperature Alloy Manufacturing

High-temperature alloys, often based on nickel, cobalt, or iron, are designed for extreme conditions. Known for their exceptional mechanical properties and corrosion resistance, these alloys perform excellently under high stress and high temperature.

Available grades: A-286, Nimonic75 / 80A / 90, GH131, GH1140, GH36, GH2706, GH2901, GH3625, GH3536, GH4169

Retain good tensile strength and ductility even at extremely high temperatures
Suitable for long-term use in oxidizing environments without significant performance degradation
Resistant to deformation under prolonged high-temperature stress
Better durability for applications subject to repeated loading
Maintain dimensional stability and mechanical performance across a wide temperature range
Despite high performance, can still be cold and hot worked and welded

Aerospace: Aircraft engine parts (e.g., turbine blades, combustion chambers), rocket engine components
Energy industry: High-temperature components in gas turbines and steam turbines such as blades and rotors
