ALODUR® ZWSK - controlled special Class
A special white aluminium-oxide grade for processes with tight quality limits, repeatability requirements and additional chemical or physical property requirements.
| What we define | Why is important |
|---|---|
| Original designation and TDS | Prevents substitution with generic fused alumina of unknown properties |
| particle-size distribution | Controls treatment intensity, profile and finish |
| critical impurities | Determines suitability for sensitive alloys and subsequent operations |
| Batch and certificate | Enable documented and repeatable delivery |
ZWSK controlled fine powders
| Imerys designation | typical laser distribution d10 / d50 / d90 |
|---|---|
| F400 | 12,8 / 20,9 / 31,8 µm |
| F600 | 7,0 / 11,5 / 17,8 µm |
| F1000 | 1,01 / 5,52 / 9,39 µm |
| F2000 | 0,47 / 1,59 / 3,92 µm |
ZWSK is not tied to one universal chemical value on the public page; the current technical data sheet for the selected variant and grit size is decisive.
