Material grades and purity

A single 99.7% white alumina seal ring standing on its lapped face on a grey granite surface plate, ground edge and mirror-flat face catching a raking side light

AL-95 · AL-995 · AL-997 | 95–99.7% Al₂O₃ | to 1,700 °C

Alumina

Pick the purity by what the part touches: 95% where cost drives the choice, 99.5% for seal faces, 99.7% for semiconductor contact.

A single ivory Y-TZP zirconia plunger lying on grey granite, its polished barrel reflecting the side light and the ground end face in focus

ZR-Y | Y-TZP, 3 mol% Y₂O₃ | to 1,000 °C

Zirconia

The highest strength and best finish of the six grades — for parts that survive sliding contact without galling the counterface.

A single dark grey-green silicon carbide nozzle on grey granite, matte sintered surface, the conical bore visible from the side

SC-S | SSiC and RBSiC | to 1,600 °C

Silicon carbide

For abrasive and thermal-shock duty — where alumina wears out and a metal part would not survive the temperature.

A pale cream machinable glass-ceramic plate with a milled rectangular pocket and a clean cut edge, resting on grey granite under side light

MG-M | mica glass-ceramic | to 800 °C

Machinable glass ceramic

Prototypes and low-volume parts milled from stock plate. Use it to prove a geometry before the pressing and sintering tool is cut.

How we hold tolerance

A diamond cylindrical grinder cutting a white alumina ring: the abrasive wheel in contact with the workpiece, a thin film of clear coolant running over it, the work zone sharp and the grey machine body falling off behind
±0.005 mmTightest tolerance heldRa 0.05 µmBest surface finish
01Green machining

Milled and drilled in the pressed, unfired state — the cheapest way to put a pocket or a slot into a ceramic part.

02Diamond grinding

External and internal grinding in the fired state, up to Ø400 mm, on diamond wheels with in-process gauging.

03Lapping and polishing

Seal faces and plunger barrels flat-lapped to Ra 0.05 µm, flatness held to 0.6 µm across the face.

04Ultrasonic and laser machining

Holes, slots and profiles in the hard-fired state, including orifices down to Ø0.2 mm.

05Metrology

CMM, roundness and surface-finish measurement on every batch, with a per-part report issued against the drawing.

What to send with your drawing

Read the machining tolerances
Which files can you quote from?

STEP, IGES, DXF or PDF drawings. A physical sample works too — we measure it and send the drawing back for confirmation before quoting.

Which grades do you hold?

AL-95, AL-995, AL-997, ZR-Y and SC-S are held in stock; MG-M and RBSiC are scheduled per furnace run.

What is the smallest order?

One piece for a prototype. Production runs are quoted by component family and grade, not by a minimum weight.

How is a drawing quoted?

Within one working day, priced per part and including the material certificate and a per-part inspection report.
