Data Standards/Certifications Applications Downloads
General Data
  • Resistance alloy as specified in DIN 46 461 (CuNi44)
  • Specific electrical resistance 0.49 ((Ω x mm²)/m)
  • Average temperature constant of the electrical resistor at 20 °C = 0.00004‑0.00008
  • Average linear thermal expansion coefficient between 20 ‑ 100 °C = 13.5 x 10‑6
  • Melting temperature 1220‑1270 °C
  • Maximum permissible wire temperature up to 600 °C
Advantages
  • Constant in specific resistance
  • Influence of the temperature or inherent heating on the resistance value practically insignificant (max. 0.8 % at 100 °C temperature rise)
  • Firmly adhering surface oxide coating withstands any temperature change and protects against further oxidation under continuous load
  • Very easy to machine thanks to softness and malleability
  • Suitable for soft soldering, hard soldering or welding

Remark
The specified wire temperatures apply for blank Isotan wires, especially unclamped in still air. Oxidized wires have a higher radiated temperature. The current load precisely required for a defined temperature can ultimately only be explicitly determined for the relations and requirements on the customer side for the specified intended use.
