Boron Carbide Parts China, Advanced Ceramics Division supplies high-quality and competitive price advanced Silicon Carbide (SiC) Tube.

SKU: SiC-T

Silicon Carbide Tube, SiC Tube

Edgetech produces sintered SiC tubes, reaction bonded SiC tubes, and recrystallized SiC tubes. Our recrystallized SiC products have high purity, while our reaction bonded and sintered silicon carbide balls have high mechanical strength. Our silicon carbide tube possesses good wearability, a low thermal expansion coefficient, extreme corrosion resistance, high hardness, and self-lubricating properties.

Silicon carbide (SiC) is a lightweight ceramic material with high strength properties comparable to diamond. It has excellent thermal conductivity, low thermal expansion, and is resistant to acid corrosion. Silicon carbide is an excellent ceramic material suitable for applications requiring good corrosion resistance and wear resistance.
