l Stainless Steel Wire
l Ultra-Fine Wires Tungsten/Molybdenum (medical guidewires, SEM probes)
l Precious Metals Gold/Silver/Platinum (jewelry, electronic contacts)
l Special Alloys NiTi/Titanium
l Industrial Wires: Copper/Aluminum (enameled wires, welding wires)
1. Engineered Crystal Structure
l (111) plane aligned with <110> drawing direction for maximum shear resistance
l Microhardness: 80-150 GPa
l Young's Modulus: 1150-1300 GPa
2. Defect-Free Performance
l No visible inclusions/cracks (20x optical microscopy inspection)
3. Proven Durability
l ＞4,000km service life in φ0.03mm copper wire production
l 85% lower cracking rate vs carbide dies in tungsten processing
4. Thermal Stability
l ＜0.005mm bore deformation at 1200℃
l Efficient heat dissipation prevents wire oxidation
HPHT Diamond vs Traditional Materials
Comparison Aspect | HPHT Diamond | PCD | Cemented Carbide |
Material Structure | Single crystal, no cracks | Grain-boundary prone | Porous, wears quickly |
Service Life | Longest-lasting | Moderate lifespan | Frequent replacement |
Precision | Mirror-smooth wire surface | Grain-induced roughness | Requires repolishing |
Cost Efficiency | Lowest total cost | Mid-range value | Low upfront, high hidden |
Versatility | Handles all metals | Struggles with soft metals | Basic copper/aluminum |
Key Takeaway:
HPHT diamond acts like an "indestructible warrior" – more durable than PCD and more precise than carbide. Slightly higher initial cost, but saves money and hassle in the long run.
