Principal applications |
|
|
|
| |
|
|
| |
These powder are mostly used in the manufacture of diamond segments by hot pressing as additives in the metal matrix to improve the diamond reteation and cutting ability. Also, these powders are used to manufacture electrical contact and tungsten carbide powders. |
