Cermet and metal–ceramic parts

Cermet blades and wear parts, and assemblies that join zirconia or alumina parts to metal by press fit, shrink fit, bonding, or pinning.

Product overview

What we make and how it is reviewed

Cermets combine ceramic hard phases with a metal binder, giving wear resistance with more toughness than plain ceramic. Metal–ceramic assemblies go the other way: they place a ceramic part only where wear, corrosion, or insulation is needed and use metal for threads, mounting, and load.

Typical requests include cermet cutting blades and wear parts, ceramic sleeves in metal housings, ceramic pump cores and valve parts in metal bodies, ceramic tips on metal shafts, and pinned or bonded inserts. The joint is usually the limiting part of the design.

Send the assembly drawing, load and temperature, and who is responsible for assembly and testing.

Product types

Part types we quote to drawing

These are made to customer drawings or samples, not sold from stock. Final material, route, and acceptance are confirmed for each drawing.

Cermet blades and wear parts

Cutting blades and wear inserts that need edge retention and some toughness.

Ceramic in metal sleeves

Ceramic sleeves and liners pressed or shrink-fitted into metal housings.

Metal–ceramic pump and valve parts

Ceramic pump cores, seats, and plungers fixed in metal bodies.

Bonded and pinned inserts

Ceramic tips and pads bonded or pinned to metal holders.

Requirements that change machining and quotation

Use the final column as a drawing and RFQ check. A requirement is easier to review when its function and acceptance evidence are stated together.

RequirementWhy it changes the routeWhat to define in the RFQ
Joint methodPress, shrink, bond, and pin joints load the ceramic differently.State the joint method or ask for a recommendation.
Thermal expansion mismatchMetal expands more than ceramic; temperature changes can loosen or crack joints.Give operating and cleaning temperature range.
Load and testThe joint must carry pressure, torque, or pull without slipping.Define load, required test (pull, torque, leak), and who performs it.

Material paths

Select against the failure mode

Cermet grades

Grade chosen for hardness and toughness balance; confirm per application.

Zirconia with steel

Zirconia expansion is closer to steel than alumina, which helps shrink fits.

Alumina with metal

Used where insulation or chemistry matters; joints need more care.

Each guide below narrows one part family or manufacturing constraint and leads back to the drawing information needed for review.

Wear-Resistant Ceramic Bushings for Industrial Machinery

Engineering guide for wear-resistant ceramic bushings, sleeves, and guide rings used in industrial machinery, including alumina, zirconia, silicon nitride, silicon carbide, ID/OD fit, roundness, Ra, counterface review, inspection evidence, packaging, and RFQ inputs.

Questions before quotation

Product RFQ FAQ

Can you supply finished metal–ceramic assemblies?

Assemblies can be reviewed. The joint method, assembly test, and responsibility are agreed in the quotation.

Engineering RFQ

Send your drawing and ceramic requirements for engineering review

Start with the part function, material or grade if known, quantity, and the critical requirements; an early-stage brief is enough to begin. If online submission is interrupted, the form prepares the same RFQ as an email instead.

  • Useful files: STEP/STP, X_T/X_B, IGES, STL, or PDF drawings.
  • Upload limit: up to 3 files, 5 MB each, 8 MB total.
  • Sensitive projects: do not send export-controlled, classified, or restricted data before an approved handling agreement is in place.
