DOMADIA™ CMSX-4 UNS N07018 Powder: Advanced Superalloy for Long-Term Reliability
Introduction
Picture this: A jet engine roaring through Himalayan altitudes, temperatures soaring, and the turbine blade—made of DOMADIA™ CMSX‑4 powder—holding its shape without fail. That’s the everyday reliability our superalloy delivers.
But what if you’ve been thinking, “High‑temp alloys are all the same?” Let’s shift that perspective: not all superalloys are created equal. The solution? CMSX‑4 powder—crafted to endure, to sustain performance under extreme heat, stress, and time.
What is DOMADIA™ CMSX-4 Powder?
DOMADIA™ CMSX-4 is a nickel-based, single-crystal superalloy powder engineered for extreme mechanical stress and heat. The single-crystal structure means it contains no grain boundaries—one of the main weak points in metals exposed to prolonged high temperatures. This design significantly improves creep resistance, fatigue life, and oxidation resistance.
Chemical Composition
| Element | Content (%) | Primary Function |
| Nickel (Ni) | Balance | Provides overall strength and high-temperature resistance |
| Chromium (Cr) | 6–8% | Improves oxidation and corrosion resistance |
| Cobalt (Co) | 9–10% | Enhances strength at elevated temperatures |
| Tungsten (W) | 5–6% | Increases creep resistance |
| Molybdenum (Mo) | 0.5–1% | Improves solid-solution strengthening |
| Aluminum (Al) | 5–6% | Forms a protective oxide layer for surface stability |
| Tantalum (Ta) | ~6% | Enhances high-temperature strength |
| Rhenium (Re) | ~3% | Increases creep rupture life and durability |
Key Properties
| Property | Performance |
| Structure | Single crystal, no grain boundaries |
| Operating Temperature | Up to ~1,200 °C |
| Creep Strength | Exceptional at prolonged high loads |
| Tensile Strength | ~1,100 MPa at 1,000 °C |
| Yield Strength | ~900 MPa at 1,000 °C |
| Oxidation Resistance | Excellent up to ~1,150 °C |
| Corrosion Resistance | High in aggressive environments |
These properties make DOMADIA™ CMSX-4 powder ideal for situations where failure is not an option.
