Material Properties & Machining Notes

The points below are for reference only. Final material selection and tolerance planning depend on grade, stock condition, part geometry, and working environment.

Key Properties

Mechanical behaviorStable for precision insulating and structural features
Temperature resistanceVery high heat resistance; depends on grade
Chemical resistanceGood in many technical environments
Dimensional stabilityUseful for small precision parts and spacers
InsulationOften selected for electrical and thermal insulation

CNC Machining Notes

  • Small holes and thin sections need careful tool selection.
  • Cutting heat should be controlled to maintain edge quality.
  • Tolerance depends on part size, grade, and geometry.
  • Surface finish requirements should be defined before quotation.
