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
