Alloy 188 cobalt powder applications by industry
| Industry | Typical parts | Why Alloy 188 cobalt | Specify in your RFQ |
|---|---|---|---|
| Aerospace combustion and exhaust | Combustor liners, afterburner and exhaust parts | Cobalt-base alloy with high-temperature strength and sulfidation resistance | Thermal cycling, joining, governing specification |
| Industrial hot-gas hardware | Burner and transition components | Oxidation and hot-corrosion resistance | Fuel contaminants, temperature profile |
Designations
- Alloy 188
- UNS R30188
- GH5188
Use Alloy 188 or UNS R30188 for chemistry-led sourcing; GH5188 is the Chinese designation. Confirm the governing specification and lot chemistry.
