Our ultrafine-grain tungsten carbide rods are specifically engineered for micro-cutting tool manufacturing, delivering consistent quality and exceptional dimensional accuracy even at extremely small diameters.

Product Application & Introduction

Product Overview

Our ultrafine-grain tungsten carbide rods are engineered specifically for manufacturing high-precision micro-cutting tools, delivering consistent quality and exceptional dimensional accuracy even at diameters as small as 0.05mm. Available in a full range of grades, they are optimized for the most demanding precision machining scenarios, including semiconductor fabrication, PCB processing, and mold manufacturing.

Core Performance Advantages

  1. 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.

  2. 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.

  3. 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.
