Why Aerospace Requires Exotic Alloys Machining

  • ✓Extreme temperature applications
  • ✓Specialized thermal expansion properties
  • ✓Superior corrosion resistance
  • ✓High strength at elevated temperatures
  • ✓Specialized magnetic/electrical properties

Typical Applications

→Turbine hot section components
→Hermetic seal housings
→Space thermal management
→High-temp exhaust systems
→Cryogenic systems
→Electronics packaging

Materials Commonly Machined

Waspaloy - Jet enginesHastelloy C-276 - Chemical resistanceKovar - Glass-to-metal sealsMP35N - Medical/aerospaceMonel 400 - Marine aerospaceInvar 36 - Low thermal expansion

Technical Considerations

  • •Each alloy requires specific machining parameters
  • •Ceramic tooling often required
  • •Very low cutting speeds
  • •Specialized coolant strategies
