Material Description

Material Number Material Name Material Number (single) Standard Standard Status Country VDA 231-106 classification Application temperature [°C]
2.0881 (DIN 17471 : 1983-04) CuNi23Mn 2.0881 DIN 17471 : 1983-04 Valid Germany 3.2 ≤ 500 1)
1) Remark: CuNi23Mn is a resistance alloy. With wire, the attainable strength is 350 N/mm². The alloy distinguishes itself by a relatively low resistivity. It has good corrosion-resistance and good scale-resistance. The upper application temperature in air is 500 °C. CuNi23Mn is well suitable for soft soldering. Application: For electric resistors of any kind, for heater wires and heater cables.
