Electrical Porcelain vs Technical Porcelain (C110)
Ceramic · grade comparison
Electrical Porcelain and Technical Porcelain (C110) are both ceramic grades. Electrical Porcelain is the stronger of the two: tensile strength 30 MPa (4.35 ksi) against 28 MPa (4.06 ksi) for Technical Porcelain (C110), about 7% more. Electrical Porcelain runs hotter in service (1,000°C vs 900°C continuous) and Technical Porcelain (C110) conducts heat better (1.5 W/m·K vs 1.2 W/m·K).

Electrical Porcelain 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.

Electrical Porcelain vs Technical Porcelain (C110) — frequently asked
Is Electrical Porcelain stronger than Technical Porcelain (C110)?
Yes. Electrical Porcelain has a typical tensile strength of 30 MPa (4.35 ksi) against 28 MPa (4.06 ksi) for Technical Porcelain (C110) — about 7% more.
Which is cheaper, Electrical Porcelain or Technical Porcelain (C110)?
Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.
When should I choose Electrical Porcelain over Technical Porcelain (C110)?
Pick Electrical Porcelain when strength drives the design, or when the part sees heat.
