In aerospace and high-performance engineering sectors, superalloy recycling & degreasing is not simply a cleaning process — it is a critical metallurgical control step that directly affects vacuum melting performance, alloy chemistry and final component integrity.
Nickel-based, cobalt-based and titanium superalloys generate high-value revert material in the form of:
- Machined turnings
- Swarf and fines
- Offcuts and solids
- Grinding residues
However, machining introduces contamination from:
- Cutting oils
- Coolants
- Lubricants
- Greases
- Carbon-based surfactants
If not properly removed before remelting, these contaminants increase carbon, sulphur and oxygen levels, affecting melt yield and compliance with aerospace specifications.
Centrifuge vs Full Swarf Washing – Aerospace Perspective
| Feature | Centrifuge | Full Swarf Washing System |
| Removes Free Oil | Yes | Yes |
| Removes Bound Hydrocarbons | Limited | Yes |
| Carbon Reduction Capability | Moderate | High |
| Suitable for Aerospace Melt Specs | Sometimes | Yes |
| Melt Yield Improvement | Moderate | Significant |
For aerospace revert alloys where carbon thresholds are tightly controlled, full aqueous degreasing provides superior contamination control.
Rotajet designs and manufactures industrial swarf degreasing systems specifically for high-value metal recovery applications.
- Controlled aqueous chemistry systems
- Carbon-reduction-focused washing processes
- Integrated drying for hydrogen control
- Modular scalable layouts
- Proven aerospace revert preparation capability
For facilities preparing revert alloys for VIM, VAR or EBM melting, Rotajet systems provide the engineered control required to maintain chemistry integrity.
