0.01mm NiChrome 8020 Ni80Cr20 Nickel Chrome Nichrome Thin Wire For Heating Element
Features:
- High Electrical Resistivity
- Excellent Oxidation Resistance
- Low Temperature Coefficient of Resistance
- Annealed Soft Temper
- Ultra fine diameter
Description:
This nickel‑chromium resistance wire delivers excellent specific resistance, superior anti‑oxidant behavior, and consistent function in high‑temperature environments. With a nominal composition of 80% nickel and 20% chromium, it endures continuous exposure to nearly 1200°C without deterioration. Its good formability allows intricate winding and shaping, while mechanical integrity persists through fluctuating heat loads. The alloy’s innate protection against scaling and chemical erosion suits it for electric heaters and thermal devices.

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.
