A single-crystal superalloy with improved creep-rupture
strength, CMSX-486 is grain boundary strengthened through optimized additions of boron,
carbon, hafnium and zirconium. CMSX-486 is designed for service as-cast, to maximize
complex casting yield without heat treatment recrystallization problems. This nickel-base
superalloy contains 9.3% cobalt, 8.6% tungsten, 5.7% aluminum, 5% chromium and 3% rhenium.

Like all of our single crystal superalloys, CMSX-486 offers
superior resistance to thermal fatigue, low-cycle fatigue and oxidation. The absence of
transverse leading and trailing edge grain boundaries enhances the performance of vanes
and vane segments.
Single-crystal alloys also demonstrate a significant improvement in
thin wall (cooled airfoil) creep properties. This makes them an important development for
turbine design because multiple airfoil segments can lower machining and fabrication costs
as well as reduce gas leakage.
