:: FAQ

Is zirconia better than alumina for plungers?

For high-pressure metering plungers, yes — zirconia's fracture toughness (8–10 MPa·m½) roughly triples alumina's, surviving edge chipping and impact. Alumina wins on cost for low-stress insulation parts.

Can you make black or blue zirconia parts?

Yes. Colored zirconia runs in the same powder-to-part chain, commonly for consumer-facing or light-sensitive applications.

What surface finish can you achieve?

Ground and lapped sealing faces to Ra 0.02–0.05 μm; as-fired surfaces Ra 0.4–0.8 μm.

Do you accept small trial orders?

Yes — prototypes from 1 piece, no MOQ for sampling.
