原材料と成分分析
What makes carbide rods so effective? The secret lies in their composition.
Tungsten carbide, the primary component, is fused with cobalt to create a compound that’s incredibly hard yet relatively tough. Here’s a closer look:
| Raw Material | パーセント | 機能 |
|---|---|---|
| 炭化タングステン（WC） | 70-97% | 硬度と耐摩耗性を提供 |
| コバルト | 3-30% | Acts as a binder for toughness |
| その他の添加物 | <1% | Enhances specific properties |
This mix is sintered at high temperatures to produce a dense, robust material that outperforms traditional steel in many scenarios.
