Product Description
WC-Ni Alloy Wear-Resistant Chute & Channel Tungsten Carbide Guide Block For Material Feeding
Our WC-Ni alloy non-magnetic guide blocks ensure smooth, precise feeding of powders, pellets, and components in semiconductor, medical, and precision assembly lines. Custom designs available. Machined from specialized WC-Ni (Tungsten Carbide-Nickel) alloy, they provide an ultra-hard, ultra-smooth, and completely non-magnetic surface to guide parts, pellets, or powders with flawless consistency in the most demanding environments.
Key Advantages
- Guaranteed Non-Magnetic Property (µ < 1.002): The use of a nickel binder instead of cobalt makes these blocks inherently non-magnetic. This is critical to prevent the unwanted attraction of ferrous particles or fines in powder handling, and to ensure zero magnetic interference in processes involving sensors, medical implants, or electronic components.
- Extreme Wear & Abrasion Resistance: With a hardness of 90-92 HRA, the guide surface resists wear from abrasive materials (e.g., ceramic pellets, metal powders, reinforced plastics) orders of magnitude longer than steel or aluminum. This maintains the critical channel dimensions and surface finish indefinitely, ensuring consistent feed rates and part orientation.
- Low Friction & Anti-Stick Surface: The material can be polished to a mirror-like finish (Ra 0.1 - 0.2 μm), significantly reducing friction and preventing materials from sticking or galling. This is essential for sticky pellets, fine powders, or delicate components.
- High Structural Rigidity: Tungsten carbide's high modulus of elasticity ensures the block does not deflect under load, maintaining precise alignment and preventing gaps that can cause jamming or mis-feeding.
Performance Comparison
| Feature | Our WC-Ni Guide Block | Hardened Tool Steel Guide | Aluminum or Stainless Steel Guide |
|---|---|---|---|
| Wear Life | Exceptional (Lasts years in abrasive service) | Moderate (Requires frequent re-machining/replacement) | Poor (Grooves quickly, changing feed dynamics) |
| Surface Finish Longevity | Permanent (Polish does not degrade) | Deteriorates rapidly with abrasion | Deteriorates rapidly |
| Magnetic Property | Non-Magnetic (µ < 1.002) | Magnetic | Slightly Magnetic (Austenitic SS) to Magnetic |
| Maintenance | Virtually None | High (Cleaning, repair, replacement) | High |
| Impact on Product Contamination | Zero (No wear debris, non-magnetic) | Possible (Steel wear debris, magnetic attraction) | Possible (Aluminum/SS debris) |
