Core Advantages
- Ultra-High Wear Resistance & Long Service Life Hardness far exceeds metals; service life can be 10–50× longer than stainless steel under frequent friction and abrasive conditions.
- High-Precision Tip & Zero Metal Contamination Mirror-polished tip does not deform, does not shed particles, and releases no metal ions — perfect for cleanroom, precision, and medical/semiconductor environments.
- Excellent Fracture Toughness (Transformation Toughening) Stress-induced t→m phase transformation creates volume expansion and compressive stress at crack tips, effectively suppressing crack propagation — achieving both extreme hardness and toughness.
Typical Applications
- Medical devices: Biopsy needle guide rods, minimally invasive surgical positioning tips, puncture assistance components
- Semiconductor / electronics testing: High-precision probes, test pins, positioning pins
- Precision measurement & positioning: CMM (coordinate measuring machine) styli, industrial probe tips
FAQ
Q1: What are the main advantages of this pointed zirconia rod compared to stainless steel needles?
A: Hardness and wear resistance are more than 10× higher, resulting in dramatically longer service life; zero metal ion contamination, ideal for clean / medical / semiconductor environments; tip maintains sharpness and precision much longer without deformation or dulling.
Q2: Can you customize single-point, double-point, or multi-point tips? What are the available diameter and length ranges?
A: Yes, fully customizable. Common diameters 3–8 mm, total lengths 50–300 mm, tip lengths 5–20 mm; number of points can be 1, 2, 3, 4 or more; tip angles can also be specified (e.g. 30°, 45°, 60°, etc.).
