When it comes to industrial tooling and machining applications, 超硬棒 are indispensable. Their pricing, however, can seem like a maze of complexity. From the raw materials to the manufacturing process, several factors influence the cost. If you’re diving into the world of carbide rods, you’re in the right place. Let’s break this down and explore everything about carbide rod pricing, including specifications, applications, and how to make the best choice for your needs.
Understanding Carbide Rods and Their Applications
超硬ロッドとは？
Carbide rods are cylindrical tools made from tungsten carbide powder mixed with a binder like cobalt. These materials are sintered under high heat and pressure, creating a hard, durable product with excellent wear resistance. You’ll find carbide rods in industries like aerospace, automotive, and manufacturing for tasks like drilling, cutting, and milling.
Key Factors Influencing 超硬棒価格
Raw Material Composition
The composition of carbide rods plays a significant role in their pricing. Tungsten carbide, the main component, is a rare and expensive material. Adding cobalt, titanium carbide, or other binders increases the cost further.
| 素材 | Composition (%) | Cost Contribution |
|---|---|---|
| 炭化タングステン | 85-95 | 高い |
| コバルト（バインダー） | 5-10 | ミディアム |
| 炭化チタン | 1-3 | 低い |
生産工程の流れ
The production process is another major cost driver. Here’s a simplified breakdown:
- パウダーの準備: Raw tungsten carbide is mixed with cobalt.
- プレス: The mixture is compacted into a rod shape.
- 焼結: High-temperature sintering creates a dense, strong material.
- 仕上げ: Polishing and coating the rod enhance its performance.
Each of these steps requires precision and specialized equipment, adding to the final cost.
