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