Description
CFC Survey Racks
Temperature Rating:
In vacuum – 5432℉ | 3000℃
Grades: PC70, PC70H, WL60, IC50
Benefits
- High strength and modulus
- Fire-resistant and dimensionally stable
- Configuration of Carbon Fabric
- Fatigue and fracture resistant. Cracks will not propagate as with molded graphite fixtures
- Lightweight and low thermal mass permitting one to load more parts in each furnace due to the material’s excellent strength to weight ratio while reducing cycle time
- Thermal deformation-resistant. CFC will remain flat and increase in strength at elevated temperatures reducing scrap and maintaining stricter part tolerances in comparison to a metal that warps over time
Applications
- Aerospace and military
- Heat treating and furnace fixtures
- Primary and secondary structures
- Windmill blades
- Brake linings, automotive, and tooling
- Solid rocket nozzles
