Ni80 Wire For Precision Equipment
Product Description
Ni80Cr20 Ni80 Round Nichrome Wire 0.03mm 0.05mm 0.1mm for Precision Equipment 

Features:

  • High Electrical Resistivity
  • Excellent Oxidation Resistance
  • Low Temperature Coefficient of Resistance
  • Annealed Soft Temper
  • Ultra fine diameter

Description:

Cr20Ni80 wire offers a balanced trade-off: high resistivity (1.08 µΩ·m) and good machinability. It can be stranded or braided for flexible heaters. The alloy’s phase stability avoids embrittlement after thousands of hours, ensuring predictable ohmic values even in vacuum or inert gas.

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.
