Mg2SiO4 vs Technical Porcelain (C110)

Ceramic · grade comparison

Mg2SiO4 and Technical Porcelain (C110) are both ceramic grades. Mg2SiO4 is the stronger of the two: tensile strength 65 MPa (9.43 ksi) against 28 MPa (4.06 ksi) for Technical Porcelain (C110), about 132% more. Mg2SiO4 is harder — 750 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 2.85 g/cm³ for Mg2SiO4) and Mg2SiO4 is stiffer (130 GPa vs 70 GPa). On the shop floor, Technical Porcelain (C110) sits in a lower cost tier (standard, $$) than Mg2SiO4 (high, $$$$).

Mg2SiO4Choose 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.
