Bare Nickel Nichrome 80 Chromel Cr20Ni80 Heating Wire For Electric Resistance

Features:

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

Description:

Cr20Ni80 combines moderate electrical conductivity with high radiant efficiency. It resists sulfur-bearing environments better than pure nickel. Suitable for ceramic kilns, it maintains shape under load. Its recyclability and stable cost make it an economical yet performance-driven solution for heavy-duty heating.

Specifications:

Applications:

• Heating Elements: Electric furnaces, industrial ovens, heat treatment equipment, kilns, and cartridge heaters.
• Household Appliances: Toasters, hair dryers, electric irons, water heaters, and rice cookers.
• Electronics: Wire‑wound resistors, rheostats, load banks, and precision potentiometers.
• Aerospace & Defense: De‑icing systems, high‑temperature sensor leads, and engine ignition components.
• Laboratory Equipment: Muffle furnaces, tube furnaces, heating mantles, and thermal analyzers.
• Automotive: Glow plugs, heated mirrors, seat heaters, and exhaust gas sensors.

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.
