1. Introduction
Cemented carbide balls, also known as tungsten steel balls, are powder metallurgy products made from tungsten carbide materials (WC, TiC) with binders like cobalt (Co), nickel (Ni), and molybdenum (Mo). They are sintered in vacuum or hydrogen reduction furnaces, offering exceptional performance in various industries.
2. Composition and Grades
| Component | Description | Common Grades |
|---|---|---|
| Carbide Powders | Micron-sized (WC, TiC), high hardness, refractory metals | YG6, YG6x, YG8, YG13, YG20, YN6, YN9, YN12, YT5, YT15 |
| Binders | Cobalt (Co), nickel (Ni), molybdenum (Mo) to hold carbide powders together | – |
