Silicon Carbide Trays

Edgetech Industries, Advanced Ceramics Division supplies high-quality and competitive price advanced Silicon Carbide (SiC) Trays.


Silicon Carbide Trays, SiC Tray


Silicon carbide (SiC) has excellent thermal conductivity, corrosion resistance, and low thermal expansion. Silicon carbide is an excellent material for sealing rings and bearings. Silicon carbide trays have excellent corrosion resistance, great wear resistance, and great mechanical strength under high temperatures. We supply many sizes of silicon carbide trays as well as other SiC products.
