Frequently Asked Questions:
-
Q: What makes DT4C suitable for high-frequency transformers?
A: Its low hysteresis loss and thin gauge options minimize heat generation at elevated frequencies. -
Q: Can you provide pre-annealed coils?
A: Yes, we offer annealing services under controlled atmosphere to optimize magnetic aging characteristics. -
Q: What packaging ensures corrosion protection?
A: Coils are wrapped with VCI paper and steel straps, with optional rust-proof coating upon request. -
Q: How does thickness affect performance?
A: Thinner gauges reduce eddy currents but require tighter flatness control – we balance both based on application needs. -
Q: Do you supply test reports?
A> Full material certification including magnetic properties is provided with each shipment. -
Q: What’s the minimum order quantity?
A> Standard MOQ is 5 tons, with trial batches available for new projects.
