OptiPowder Ni718 is engineered for advanced manufacturing and is particularly suited for applications requiring high-temperature resistance, with the ability to withstand temperatures up to 1200°C (2200°F). This makes it ideal for components used in aerospace, power generation, and automotive industries. Its high strength, fatigue resistance, and creep resistance make it perfect for stress-critical components in demanding environments.
In the aerospace sector, Ni718 is used for turbine blades, rocket motors, and combustion chambers, providing the strength and oxidation resistance needed to endure extreme conditions. In the oil and gas sector, Ni718 is used for components exposed to corrosive environments, ensuring long-term durability. For industrial gas turbines, Ni718 maintains both reliability and efficiency, preserving mechanical integrity and performance under extreme operating temperatures. Additionally, Ni718 is widely utilized in fuel cell technologies, including Solid Oxide Fuel Cells (SOFCs), due to its stability in both high and low temperature environments.
OptiPowder Ni718 supports various AM processes, including:
- Laser Powder Bed Fusion (LPBF): Ideal for producing complex parts with high accuracy and mechanical properties.
- Electron Beam Melting (EBM): Suitable for creating large, complex parts with excellent mechanical properties.
- Binder Jetting: A cost-effective AM process for producing larger parts with lower density and porosity.
Continuum Powders offers OptiPowder Ni718 in various particle size distributions (PSD) to meet your specific manufacturing needs. Representative properties shown here are for laser powder-bed fusion (LPBF) powder PSD.
