Constantan wire

It is a resistance alloy with copper and nickel as the main component. Features: Low temperature coefficient of resistance, wide operating temperature range (below °C), good processing performance, and good welding performance.
Main uses: Mainly used for making electronic components in instrumentation, electronics and industrial equipment.
