Product Description
High Temp Nichrome 70 Cr30Ni70 Ni70 Wire Nickel Chrome Alloy Wire For Soldering Iron

Features:

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

Description:

The thermal expansion coefficient of nichrome is moderate (about 13–14×10⁻⁶/°C), which helps minimise thermal stress during rapid heating and cooling. This characteristic, combined with good thermal conductivity, reduces the risk of cracking or warping, allowing the wire to withstand frequent on‑off cycling without mechanical failure.

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.
