Finished surface of Tungsten sheets / plates

| Finished surface | Surface roughness (µm) (Typical value) |
Feautures |
|---|---|---|
| Rolled | Ra3.0 | This is the most common tungsten sheets / plates. Plates with a thickness of 3 mm or less can be heated, bent, and pressed. We also offer tungsten sheets / plates that have been sufficiently deformed to facilitate cutting and polishing processes. |
| Mirror | Ra1.6 | This tungsten sheet has been repeatedly rolled to reduce the unevenness of the surface and to add luster to the sheet. |
| CC | Ra2.9 | Acid cleaning is applied to reduce variations in surface conditions caused by rolling. |
| Cutting | Ra2.0 | If greater precision is required than what is achieved with the rolling finish, the surface is machined. |
| Polishing | Ra0.6 | If you require a higher degree of precision or smoother surface roughness than can be achieved through cutting and finishing, polishing is an option. |
| Horning | Ra2.5 | Material blasted with alumina abrasive. |
