Alumina 99.5 vs C-510 High-Alumina Refractory
Ceramic · grade comparison
Alumina 99.5 and C-510 High-Alumina Refractory are both ceramic grades. C-510 High-Alumina Refractory is lighter (2.9 g/cm³ vs 3.9 g/cm³ for Alumina 99.5) and Alumina 99.5 is stiffer (372 GPa vs 100 GPa). On the shop floor, C-510 High-Alumina Refractory sits in a lower cost tier (budget, $) than Alumina 99.5 (high, $$$$).
C-510 High-Alumina RefractoryChoose it when weight is the constraint, or when cost is the deciding factor.
Alumina 99.5 vs C-510 High-Alumina Refractory: 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.
