Description:
Developed for extreme thermal cycling, this ultra‑thin resistance wire maintains structural integrity at temperatures that degrade standard alloys. Its nickel‑chromium matrix prevents sagging and embrittlement, ideal for furnace components, heat‑treating fixtures, and cartridge heaters. Strict dimensional tolerances guarantee uniform resistance per foot for accurate load calculations. It withstands repeated heating cycles without deformation.

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.
