FAQ
Q: Are your coils compatible with long-term implantable devices?
A: Yes! Our Type MD-4 coils pass 10-year simulated aging tests per ASTM F2129.
Q: Can you provide coils pre-cut to catheter tooling dimensions?
A: Absolutely. Laser-cutting precision down to 0.1mm tolerance for minimally invasive devices.
Q: How do you ensure surface cleanliness for surgical applications?
A: Triple ultrasonic cleaning + nitrogen-purged vacuum sealing (per IEST-STD-CC1246D).
Q: Do you support custom annealing for low-magnetic memory?
A: Yes, our proprietary zero-remanence annealing process reduces residual magnetism by 99%.
