Overview
Why Choose Thermal Expansion Alloys?
Thermal expansion alloys are well suited to investment casting applications requiring precise tolerances and resistance to thermal fluctuations. Consider thermal expansion alloys when your parts require:
- Low coefficient of thermal expansion (CTE)
- Exceptional temperature stability
- Dimensional control
- CNC machining
