SiC
Silicon Carbide Ceramics
Silicon carbide for the most demanding thermal and abrasive duty: very high service temperature, thermal shock and aggressive wear.

Ceramic Wear Parts
Liners, guides, bushes and contact parts that outlast metal where surfaces abrade or gall.
A wear part is bought against a replacement interval. The useful question is not which ceramic is hardest, but what is actually removing material — sliding abrasion, impact, galling against a mating surface, or corrosion that softens the surface first.
That answer decides the grade, and it also decides the fixing: a liner that is clamped can be a different material and thickness from one that is bonded, because the loads go into it differently.
Specification and control points
| Material system | Alumina · Silicon carbide · Zirconia |
|---|---|
| Contact geometry | To drawing |
| Wear face thickness | To drawing, set by the expected interval |
| Fixing | Bonded · Clamped · Bolted · Slotted in as drawn |
| Contact face finish | As-fired or ground |
| Replacement | Removable in place, or a fixed wear surface |

Made to your requirement
What is defined with you before production
- What removes the material: medium, particle size, speed, or load
- The fixing method and the thickness available for it
- Whether the part must be replaceable in place
- The duty cycle and the interval you are trying to reach
Supply stage
Sample part first, then batch production on the same material and process basis. Ask for the material data sheet with your quotation.
