OptiPowder M247/M247LC
High-Performance Nickel Alloy for Advanced Manufacturing
Download Datasheet
Continuum OptiPowders are produced by our proprietary M2P Gas Atomization System. This advanced plasma-based process transforms metal revert streams into high-quality spherical powder in a single step. By utilizing 100% reclaimed feedstock and green energy sources, this process significantly reduces the carbon footprint while delivering exceptional material performance.
Material Overview
Nickel superalloy M247 is a precipitation-strengthened Ni-based alloy with significant additions of chromium, aluminum, tantalum and tungsten, designed for extreme high-temperature applications up to 1,000°C. It offers superior oxidation and corrosion resistance, exceptional creep strength, and high-temperature stress rupture properties. This alloy is primarily found in applications where high temperature corrosion resistance is required such as gas turbine components.
M247 is widely used in aerospace, industrial gas turbines, and energy applications, particularly for components subjected to extreme thermal and mechanical stress under corrosive atmospheres. The low-carbon version (M247LC) is specifically designed for rotating components such as turbines and impellers, where extended fatigue life is critical.
