Product Application & Introduction
Product Overview
Core Performance Advantages
- Grain Size Optimization
Ultra-fine grain (0.4μm grades: JX25U, JX09U, JX06U): Provides superior hardness and wear resistance, ideal for finishing operations and high-wear applications.
Fine grain (0.7–1.0μm grades: JX20, JX06, JX40): Balances hardness with toughness, suitable for heavy cutting and impact-prone tasks.
- Cobalt Content Tailoring
High cobalt (12–15% grades: JX25U, JX40): Maximizes toughness and impact resistance, perfect for high-speed stamping dies and interrupted cutting.
Low cobalt (6–9% grades: JX06, JX09U, JX06U): Delivers maximum hardness and wear resistance, ideal for long-life cutting tools in abrasive materials.
- Precision & Stability
Tight diameter tolerance of ±0.002–±0.005mm ensures tool consistency.
Exceptional straightness (≤0.001mm/100mm) minimizes runout during high-speed machining.
High density (≥99.9%) guarantees uniform performance across the entire rod length.
Target Applications
| Application Area | Recommended Grades | Key Benefits |
|---|---|---|
| Semiconductor & Chip Manufacturing | JX25U, JX09U, JX06U | Ultra-fine grain ensures precision in micro-milling and drilling of wafers and packaging substrates, maintaining dimensional accuracy for 7nm+ advanced processes. |
| PCB & Substrate Processing | JX20, JX25U | High wear resistance enables tens of thousands of holes per drill, reducing tool change frequency and improving production efficiency. |
| Precision Mold Making | JX40, JX06U | High toughness and wear resistance extend the lifespan of mold cores, ejector pins, and stamping tools. |
| General Precision Machining | JX20, JX06 | Versatile performance across carbon steel, stainless steel, aluminum alloys, and plastics, suitable for general-purpose end mills and drills. |
