OptiPowder Ni7208
High-Strength Nickel Superalloy for Demanding Thermal Environments
OptiPowder Ni7208 is a high-performance nickel-based superalloy specifically engineered for high-temperature stability, up to 1000ºC.
This is a popular choice of alloy where elevated temperature creep strength and low cycle fatigue resistance are needed. Such applications include gas turbine hot section components such as combustors, impellers, turbines, and liners.
The alloy is also sought after for the silencers or suppressors due to its high resistance to low cycle fatigue. Excellent formability and weldability make this alloy attractive for advanced manufacturing.
Continuum produces OptiPowder Ni7208 using our proprietary M2P Gas Atomization System that uses 100% recycled feedstock, reducing the Powder Carbon footprint by 99.7%.
This advanced plasma atomization process transforms reclaimed superalloy feedstock into high-quality, spherical powder in a single step— powered by renewable energy sources to minimize environmental impact. The result is a premium grade, high performance powder optimized for various additive manufacturing (AM) platforms.
