Mullite vs Technical Porcelain (C110)
Ceramic · grade comparison
Mullite and Technical Porcelain (C110) are both ceramic grades. Mullite is the stronger of the two: tensile strength 80 MPa (11.6 ksi) against 28 MPa (4.06 ksi) for Technical Porcelain (C110), about 186% more. Mullite is harder — 1,100 HV against 600 HV for Technical Porcelain (C110) — which matters for wear surfaces and threads. Technical Porcelain (C110) is lighter (2.4 g/cm³ vs 2.9 g/cm³ for Mullite) and Mullite is stiffer (150 GPa vs 70 GPa). On the shop floor, Technical Porcelain (C110) sits in a lower cost tier (standard, $$) than Mullite (premium, $$$).
MulliteChoose it when strength drives the design, or when surface hardness matters.
Technical Porcelain (C110)Choose it when weight is the constraint, or when cost is the deciding factor.
Mullite vs Technical Porcelain (C110): propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all ceramic grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.
