Zirconia Ceramic Parts
High toughness zirconia parts for wear surfaces that run against metal, fluid or fibre without picking up magnetism or corroding.

Ceramic Materials And Ranges
Pick the family by the property the part needs. Every range is made to drawing as well as in the standard sizes shown.
Five Material Families Seven Ranges
Zirconia, alumina, steatite, silicon carbide and silicon nitride, grouped the way we actually quote them.
Al2O3 Alumina Ceramic Parts
95% and 99% alumina rings, tubes, substrates and plates for insulation, wear and high temperature service up to 1650C.
See the range
Steatite Ceramic Parts
Talc based steatite beads, strips and insulators for electrical heating assemblies where dielectric strength matters more than toughness.
See the range
Metallized Ceramic Parts
Mo/Mn metallized and plated alumina ready for brazing into vacuum interrupters, feedthroughs and hermetic assemblies.
See the range
SSIC And SIC Parts
Silicon carbide rings, cylinders and seal faces for abrasive slurry and hot gas duty where alumina wears through too quickly.
See the range
Ceramic Blades And Knives
Zirconia and silicon nitride blades for clipper heads, slitting and shearing tools that dull or corrode when made from steel.
See the range
Machinery Ceramic Parts
Discs, pistons and wear parts that go straight into pumps, taps and textile machinery as a drop-in replacement for metal.
