Frequently Asked Questions
Q: What makes DT4A suitable for electromagnetic applications?
A: DT4A offers exceptional magnetic softness characterized by high permeability and low hysteresis loss, enabling efficient magnetic flux transfer with minimal energy dissipation.
Q: Can you supply diameters other than 19mm?
A: Yes, we offer various diameter options ranging from 5mm to 50mm. Contact our technical team with your specific requirements.
Q: What surface finish can be expected?
A: Our cold-drawn bars feature a smooth surface with Ra ≤ 0.8μm, suitable for most applications without additional machining.
Q: Do you provide material certification?
A: Standard mill test certificates are available upon request, providing chemical composition and mechanical property verification.
Q: What packaging options are available?
A: We offer protective bundling with steel straps, wooden crating for international shipments, or custom packaging solutions based on your logistics requirements.
Q: How does cold-drawing affect magnetic properties?
A: The cold-working process refines the grain structure, enhancing permeability while reducing core loss compared to hot-rolled alternatives.
Q: What is your minimum order quantity for custom lengths?
A: MOQ for custom lengths starts at 500kg, though we can accommodate smaller quantities for established customers.
Q: Can you supply cut-to-size pieces?
A: Yes, we offer precision cutting services to deliver ready-to-use components, reducing your processing time and material handling costs.
