Frequently Asked Questions (FAQ):
Q1: Can you achieve tolerances tighter than ±0.05mm?
A1: Yes, tighter tolerances (e.g., ±0.02mm) are achievable for specific diameters upon request, subject to technical review and feasibility.
Q2: What is the minimum order quantity (MOQ) for custom diameters?
A2: Our standard MOQ starts at 100 pieces. However, we offer flexibility for R&D or prototype quantities – please inquire for details.
Q3: Do you provide any surface coating for corrosion protection?
A3: Standard rods are supplied bare. Electroless nickel plating or other protective coatings are available as an optional service to prevent oxidation.
Q4: How does DT4C compare to other soft magnetic alloys like Permalloy?
A4: DT4C offers higher saturation flux density (~2.15T) than many nickel-iron alloys, making it suitable for applications requiring higher flux levels, often at a more economical cost. Permalloy may offer higher initial permeability in very low fields.
Q5: What is the typical lead time for standard sizes?
A5: Standard diameters and lengths typically ship within 2-3 weeks. Lead times for custom specifications vary based on complexity and volume – we provide firm timelines upon order confirmation.
Q6: Can you supply rods with specific magnetic annealing treatments?
A6: Yes, controlled atmosphere annealing to optimize magnetic properties (e.g., decarburization, stress relief) is a standard offering to meet specific application requirements.
Q7: Do you offer machining services on these rods (e.g., threading, center drilling)?
A7: Secondary machining services are available. Please provide your detailed requirements for a comprehensive quote.
Q8: What documentation accompanies shipments?
A8> Each shipment includes a Material Certificate (including chemical composition and magnetic property data if specified) and a Dimensional Inspection Report.
