Silicon Carbide vs TiN
Ceramic · grade comparison
Silicon Carbide and TiN are both ceramic grades. Silicon Carbide is harder — 2,500 HV against 1,900 HV for TiN — which matters for wear surfaces and threads. Silicon Carbide is lighter (3.15 g/cm³ vs 5.22 g/cm³ for TiN) and Silicon Carbide is stiffer (410 GPa vs 250 GPa).

Silicon Carbide vs TiN: 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.

Silicon Carbide vs TiN — frequently asked
What is the difference between Silicon Carbide and TiN?
Silicon Carbide and TiN are both ceramic grades. Silicon Carbide is harder — 2,500 HV against 1,900 HV for TiN — which matters for wear surfaces and threads. Silicon Carbide is lighter (3.15 g/cm³ vs 5.22 g/cm³ for TiN) and Silicon Carbide is stiffer (410 GPa vs 250 GPa).
Which is cheaper, Silicon Carbide or TiN?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, Silicon Carbide or TiN?
TiN, by a small margin. Both rate not recommended for machinability — 8/100 against 3/100 for Silicon Carbide.
