  • Low Expansion Alloy Forgings
Low expansion superalloys have excellent mechanical properties and low thermal expansion coefficient simultaneously at temperatures below 650℃, and some can be used up to 750℃ because of excellent oxidation resistance and low thermal expansion coefficient. This series of superalloys are mainly used for clearance control rings of aero engines, large-size bolts of ultra-supercritical generator set etc. Currently, Gaona can provide bars and rings of various low expansion superalloys with different sizes to customers according to their requirements.
