Overview
OptiPowder M247LC is a precipitation-strengthened nickel-based superalloy designed for extreme high-temperature environments. With significant additions of chromium, aluminum, tantalum, and tungsten, the alloy delivers excellent oxidation and corrosion resistance, along with exceptional creep strength and stress rupture performance at temperatures approaching 1,000°C.
The low-carbon variant of Mar-M247 is engineered to improve ductility and fatigue performance, making it particularly well-suited for rotating components and applications requiring extended service life under cyclic loading.
OptiPowder M247LC is engineered for high-temperature, high-stress environments, including:
Aerospace turbine blades, vanes, and hot-section components
Industrial gas turbines and power-generation systems
Rotating components such as impellers and turbine wheels
Energy applications requiring creep resistance and thermal stability

Additive Manufacturing Process Compatibility
OptiPowder M247LC supports a range of AM and advanced manufacturing processes, including:
Laser Powder Bed Fusion (LPBF):
High-temperature, high-performance components with complex geometries
DED and other advanced routes:
Where alloy control and thermal performance are critical
Binder Jetting (MBJ)
Cost-effective production of turbine and energy components prior to densification
Hot Isostatic Pressing (HIP):
Full-density consolidation and improved mechanical performance
Available PSDs & Customization
OptiPowder M247LC is available in multiple particle size distributions, including 0–32 µm, 0–45 µm, 15–45 µm, 45–106 µm, and HIP-grade material, with custom PSDs, blended distributions, and program-based supply available on request to support specific process requirements and qualification needs.

Morphology
Powder morphology is predominantly spherical with minimal satellites, with no hollow particles, excessive agglomeration, or foreign-object defects visible at ~300× magnification.
Blending
Multiple heats may be blended into a single lot when each heat independently meets all chemical and PSD requirements.
Certification
Each shipment includes a certificate of analysis reporting chemical composition, particle size distribution, and any additional agreed-upon test results demonstrating conformance to specifications.
