Ceramic Composite Washers

Ceramic Composite Washers (CMCs) are advanced components used in conjunction with bolts and nuts to evenly distribute load, prevent damage to mating surfaces, and provide electrical or thermal insulation. Manufactured from Ceramic Matrix Composites (CMCs) such as SiC/SiC or Oxide/Oxide systems, these washers offer the unique ability to maintain their structural integrity and stiffness at extremely high temperatures (up to $1650^\circ C$) while being significantly lighter than metallic counterparts. They are essential for securing lightweight, high-temperature components in aerospace engines, nuclear applications, thermal processing equipment, and specialized structural assemblies where high heat and wear resistance are mandatory. Zeron Fastners supplies CMC washers to precise specifications for demanding fastener systems.
