介绍CBX CUPRON® alloy, which is produced gas free, has a practically constant resistance over a wide temperature range. It overcomes two significant disadvantages of conventional Constantan-the relatively high difference in the temperature coefficient of resistance (TCR) between the low and high temperature range and the generation of gas when Constantan is placed in contact with glass, enamel, or ceramic type materials. By overcoming these deficiencies, it has been used in resistors that are vitreous enameled, glass or ceramic coated, or even bare.

CBX CUPRON alloy has been supplied as fine wire and ribbon for precision resistors because of its low TCR and its stability of resistance. It has also been used in resistors, rheostats, or shunts for use in power controls up to a maximum temperature of 538°F (281°C). It has commonly been used in AC components.

Care must be taken in termination of CBX CUPRON alloy when it is joined to copper because of the high thermal EMF generated. This requires both terminals to be at the same temperature for DC resistors.

The temperature coefficient of resistance of CBX CUPRON alloy is ± 25 ppm per degree C between -67° and 221°F (-55° and 105°C). The resistance curve is more linear with temperature than for Constantan alloys. Instead of a nominal difference of 20 ppm per degree centigrade between the cold range (-67° to 77°F [-55° to 25°C]) and the hot range (77° to 221°F [25° to 105°C]), the differential is reduced by a factor of approximately two.
