Silicon Carbide (SiC) is one of the hardest and most thermally stable advanced ceramics available. It is ideal for high-precision CNC machining in applications demanding extreme wear resistance, high strength, and thermal shock performance. Commonly used in semiconductor, aerospace, energy, and industrial processing equipment.
Silicon Carbide (SiC) is a sintered ceramic compound composed of silicon and carbon. Known for its exceptional hardness and heat resistance, SiC is widely used in applications where high thermal conductivity, corrosion resistance, and structural integrity are critical.
We offer CNC machining for high-purity sintered Silicon Carbide (SiC).
