Silicon carbide (SiC) is a lightweight ceramic material with high-strength properties comparable to diamond. It has excellent thermal conductivity, high mechanical strength, low thermal expansion, chemical resisitance, and thermal shock resisitance. Silicon carbide is an excellent ceramic material for applications requiring good erosion and abrasive resistance. Consequently, it is useful in a variety of applications including spray nozzles, shot blast nozzles, and cyclone components.
Silicon carbide materials are ideal for sealing rings and bearings. Silicon carbide seal rings have excellent corrosion resistance, great mechanical strength under high temperatures, and great wear resistance. We supply multiple sizes of silicon carbide rings as well as other SiC parts.
Advanced Ceramic Materials (ACM) supplies silicon carbide seal rings with different materials to fulfill various requirements of our customers. We provide flat silicon carbide rings, single and double-stepped silicon carbide rings, and custom-manufactured silicon carbide rings with complex shapes.
