Introduction
Interpretation of core technical parameters
Comparison of chemical composition requirements
| Grade | Ni+Co content | Impurity limit (typical value) | Applicable scenarios |
|---|---|---|---|
| F-N4 | ≥99.9% | Cu≤0.015% | High-precision aviation components |
| F-N6 | ≥99.5% | Fe≤0.100% | General industrial parts |
Key indicators of physical properties
Particle size distribution calculation table:
| Category | D10(μm) | D50(μm) | D90(μm) |
|---|---|---|---|
| Class I | 15-25 | 30-45 | 50-65 |
Technology evolution and selection recommendations
Technological innovation from traditional powder metallurgy to additive manufacturing promotes the progress of particle size: the 15-25μm fine particle size of Class I powder meets the stacking accuracy requirements of the SLM process. Compared with the 2015 version of the enterprise standard, the tap density index is increased by 8.3% to ≥6.20g/cm³
Typical application cases
- An aviation company uses Class I F-N4 nickel powder to manufacture combustion chamber components, achieving a wall thickness accuracy of ±0.15mm
- Turbine blade repair uses Class III F-N6 powder, and the deposition rate is increased to 360cm³/h
Key points of quality control
| Test items | Instrument recommendation | Arbitration method |
|---|---|---|
| Oxygen content | Pulse heating infrared instrument | GB/T11261 |
| Hollow powder rate | Scanning electron microscope + image analysis | Buyer agreement |
Special warning: Class I powder must be used in a <4hRH environment
