C-510 High-Alumina Refractory vs Synthetic Sapphire
Ceramic · grade comparison
C-510 High-Alumina Refractory and Synthetic Sapphire are both ceramic grades. C-510 High-Alumina Refractory is lighter (2.9 g/cm³ vs 3.98 g/cm³ for Synthetic Sapphire) and Synthetic Sapphire is stiffer (400 GPa vs 100 GPa). On the shop floor, C-510 High-Alumina Refractory sits in a lower cost tier (budget, $) than Synthetic Sapphire (high, $$$$).
C-510 High-Alumina RefractoryChoose it when weight is the constraint, or when cost is the deciding factor.
C-510 High-Alumina Refractory vs Synthetic Sapphire: 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.
