| 1) Remark: CuNi3 is a resistance alloy. With wire, the attainable tensile strength is 290 N/mm². The resistivity is very low with a relatively small temperature coefficient. The upper application temperature in air is 200 °C. The resistance to atmospheric corrosion is high. CuNi3 is of good suitability for soft soldering. Application: Low-ohm electric resistors for low stress. |
