Silicon carbide ring is made of high purity silicon carbide materials, it is ideal for sealing rings and bearings. Silicon carbide rings have excellent corrosion resistance, great mechanical strength under high temperatures and great wear resistance. It has excellent thermal conductivity, low thermal expansion and thermal shock resistance. We provide flat silicon carbide rings, single and double stepped silicon carbide rings, and custom manufactured silicon carbide rings with complex shapes.
– High strength over a broad temperature range
-Moderate thermal conductivity
-Low coefficient of thermal expansion
-Moderately high elastic modulus
-Excellent thermal shock resistance
-Ability to withstand high structural loads to high temperature
-Superior wear resistance
-Unusually high fracture toughness
