Material Description

Material Number Material Name Material Number (single) Standard Standard Status Country VDA 231-106 classification Application temperature [°C]
2.0802 (DIN 17471 : 1983-04) CuNi2 2.0802 DIN 17471 : 1983-04 Valid Germany 3.2 ≤ 300 1)
1) Remark: CuNi2 is a resistance alloy. With wire, the attainable tensile strength is 220 N/mm². The resistivity is very low. The resistance to atmospheric corrosion is high. The upper application temperature in air is 300 °C. CuNi2 is of good suitability for soft soldering. Application: Terminal studs, low-ohm electric resistors, heater wires, heater cables with low heating temperature.
