FAQ
Q1: Which grade should I choose for my application?
A: For maximum operating temperature up to 1300°C, choose Cr10Ni90. For general heating elements up to 1200°C, Cr20Ni80 is the industry standard. For cost sensitive projects with lower temperature requirements (≤1100°C), consider Cr20Ni35 or Cr20Ni30.
Q2: Can I get a sample before bulk order?
A: Yes, free samples of any grade are available upon request if in stock. You only pay shipping.
Q3: What is the lead time?
A: Samples ready in 2–3 days. Mass production takes 7–20 working days depending on quantity and grade.
Q4: Is there a minimum order quantity (MOQ)?
A: MOQ is 5 kgs.
Q5: How do you prevent the wire from tangling during shipping?
A: We wind on anti static plastic spools and seal in protective boxes. Each spool is inspected under magnification.
Q6: Do you offer a warranty?
A: Yes, 12 month warranty against manufacturing defects. Mill Test Reports (MTRs) are available with full batch traceability.
