Constantan alloy
Constantan alloy is a resistive alloy with copper and nickel as the main components (40% nickel, 1.5% manganese), which is suitable for making variable resistance and strain resistance components for AC instruments. It has a low resistance temperature coefficient, a wide operating temperature range (below 480℃), good machinability, corrosion resistance and easy brazing. It is suitable for use in AC circuits, precision resistors, sliding resistors, resistance strain gauges, etc. It can also be used for thermocouples and thermocouple compensation wire materials.
Kang copper alloy has a low resistance temperature coefficient, a wide range of temperature (480 ℃ below), good mechanical processing properties, corrosion resistance and easy brazing characteristics. It is suitable for use in AC circuits, precision resistors, sliding resistors, resistance strain gages, etc. It can also be used for thermocouples and thermocouple compensation wire materials.
In addition, there is a new Kang copper resistance alloy, copper-iron-based alloy, which has the same resistivity as Kang copper, the basic similar resistance temperature coefficient, and the same operating temperature. Compared with KangCu resistance alloy, new KangCu has the advantage of lower price because it does not contain higher price of nickel, but the oxidation resistance is worse than KangCu. It can replace copper wire resistance alloy in many aspects.
Methods to change the temperature coefficient of resistance of copper composite alloys
Through the analysis of the structure of the KangCu alloy, it is known that the resistance temperature coefficient of KangCu alloy can be adjusted in the following ways:
1, adjust the percentage of Ni to adjust the resistance temperature coefficient.
2、Add impurity elements such as iron, manganese, silicon, magnesium, etc., to increase the character distortion of the KangCu alloy to adjust the resistance temperature coefficient.
3、Cold processing of copper-containing alloys to change the internal defects of copper-containing alloys to adjust the resistance temperature coefficient.
4、Heat treatment of copper-containing alloys to change the internal defects of copper-containing alloys to change the resistance temperature coefficient of copper-containing alloys
