Product Description

Constantan Alloy Wire:

Constantan is based on copper-nickel as the main component of the resistance alloy.

Product Details:
Grade: 6J40
Nature: With 40% nickel, 1.5% copper manganese alloy

Characteristics: With a lower temperature coefficient of resistance, the use of a wide temperature range (500 degrees Celsius) good machining properties, corrosion resistance and easy soldering.
Thermoelectric power of high copper, the exchange of instruments can be made of the variable resistors and strain resistive element.


Our products have the following features: Stable performance, high resistivity, high working temperature, allowable high surface load, small specific gravity and reasonable price.

Mainly uses in the electric car controller, the instruments and meters, the integrated circuit, the sample electric current, the resistor. And low pressure resistance and so on.

Delivery: Normally 10-15 days after receive deposit, according to the quantity
