GH4105 / GH105 Nickel-Based Superalloy: High-Temperature Strength for Extreme Environments
GH4105 / GH105 Nickel-Based Superalloy: High-Temperature Strength for Extreme Environments
1. About GH4105 GH4105, also designated GH105 or Nimonic 105 (W.Nr. 2.4634), is a premium precipitation-hardened wrought nickel-cobalt-chromium superalloy that delivers exceptional tensile strength, outstanding high-temperature oxidation resistance, and a stable microstructure under sustained thermal cycling. It is purpose-engineered to operate reliably at continuous service temperatures ranging from 750 °C up to 950 °C, serving core extreme-condition scenarios including commercial and military aerospace engines, heavy-duty industrial gas turbines, clean energy power generation units, and high-temperature petrochemical equipment. 2. Key Features Excellent mechanical performance at elevated temperatures up to 950 °C High resistance to thermal fatigue and oxidation Good formability for precision manufacturing processes Long service life in demanding high-temperature environments Precipitation-hardened microstructure for superior creep-rupture strength 3.
