Carbon Carbon Composite
(Carbon Fiber Reinforced Carbon Matrix Composites)Originally developed for the aerospace industry, Carbon/Carbon composites have now been recognized to provide an extremely cost effective solution for furnace fixture applications. The unique attributes of Wealson Carbon/Carbon composites offer important advantages over both metal and graphite fixtures.
Carbon/Carbon Composite Nuts, Bolts, Channels and Tubes
Wealson manufacturing technology allows a wide variety of sizes and geometries to be fabricated.
We would welcome the opportunity to discuss which grade is best suited to your application.
Features:
Negligible Thermal Deformation: Unlike metal fixtures, which twist and warp over time, Carbon/Carbon composites will remain flat and actually increase in strength at elevated temperatures. You reduce scrap and maintain tighter part tolerances.
Low Thermal Mass: The high strength to weight ratio and low specific heat of Carbon/Carbon composites allow you to load more parts in each furnace and reduce the cycle time.
Excellent Fracture Resistance: Cracks will not propagate catastrophically as occurs with molded graphite fixtures.
Application:
Wealson CFC Material as monosilicon or polysilicon furnace heaters,crucibles,fasten Parts and insulation plates with various shapes.
