Machines for production glass-covered microwires
The metallic nucleus of microwire can be produced from:
- Pure metal: Ag, Au, Cu, Ni, Pt …
- Resistive Cu-Ni-Si-Mn, Ni-Cr-Si … composition alloys
- Magnetic amorphous Fe-B-Si, Co-Fe-B-Si, Co-Mn-B-Si …
- Composition alloys with:
- Natural Ferromagnetic Resonance (up to 8 GHz)
- Magnetic Bistable Behavior
- High Permeability at Frequencies up to 30 MHz
- GMI
The following metallic nucleus diameters can be obtained for:
| Cu, Ag, Au | 5 – 40 µm |
| Ni, Pt | 3 – 20 µm |
| Cu-based alloys | 2 – 25 µm |
| Ni-based alloys | 1 – 20 µm |
| Fe-B-Si based | 1 – 20 µm |
| Co-Mn-B-Si based | 3 – 25 µm |
| Co-Fe-B-Si based | 3 – 25 µm |
Technical characteristics:
The Installation is joined to three-phase 380 V power voltage of frequency 50 Hz. Microwire cooling liquid either water or oil. The Installation needs in cooling water. Consumption – not less then 10 l/min. Power supply is 10 kV×A. The HF power supply provides oscillating power 8 kV×A of frequency 440 kHz. The rate of microwire casting up to 500 m/min. The length of unbroken not less than 500 m.
