Sharpest Tungsten Needle for sale
Lead Manufacturer from China
If you’re working in microdissection, wafer testing, ion emission, or high-voltage discharge, selecting the sharpest tungsten needle is not just a matter of preference—it’s mission critical. In this guide, I’ll walk you through what makes a tungsten needle truly sharp, how to evaluate its precision, and where to source verified, customizable options backed by real-world data and engineering standards.
Quick Answer:
The sharpest tungsten needle typically features a tip radius of just 50 nanometers, offering unmatched precision for microdissection, semiconductor testing, and ion emission. These needles are produced using ultra-fine machining and surface polishing techniques and must meet tight tolerances of ±0.001mm to ensure consistent performance across demanding applications.

What Defines the Sharpest Tungsten Needle?
Nano-Scale Tip Radius
The defining factor of a needle’s sharpness is its tip radius. In high-precision settings, a tip radius of 50 nanometers (0.05μm) qualifies as ultra-sharp.
🧠 Why it matters:
The finer the tip radius, the lower the contact area—making it ideal for clean cuts in microdissection, precise contact in electronics testing, or stable discharge in ion systems.
| Material | Typical Tip Radius | Application |
|---|---|---|
| Tungsten | 50nm | Microdissection, wafer testing |
| Platinum | 150nm | Biochemical sensing |
| Stainless Steel | 200–300nm | Standard probes, general industrial |

Material Properties You Can Trust
Tungsten is chosen for its exceptional physical properties that make it suitable for demanding applications:
- Melting Point: 3,422°C – The highest of all metals.
- Hardness: 9.0 on Mohs scale – Ensures exceptional wear resistance.
- Purity: ≥99.95% required for scientific and medical use.
- Density: 19.25 g/cm³ – Provides rigidity and durability.
These values are verified across ASTM standards, ISO certifications, and scientific publications such as Nature Materials and Microscopy Today. Tungsten’s combination of superior thermal stability and mechanical strength ensures consistent performance even under extreme conditions.
Precision Manufacturing Techniques
A tungsten needle’s sharpness depends heavily on its manufacturing process. Advanced techniques ensure precision at nanoscale levels:
- Centerless Grinding: Guarantees consistent shaft diameter across batches.
- Micropolishing: Provides a smooth surface finish for non-stick applications in biomedical or electronic fields.
Ion Beam or EDM Tapering: Shapes ultra-sharp points with tip radii as fine as 50 nanometers.
- Measurement Tolerances: Controlled by coordinate measurement machines (CMM) to ±0.001mm accuracy.
