CBX Cupron®
CBX Cupron, which is produced gas free, has a practically constant resistance over a wide temperature range. Key benefits of this alloy include:
- Exceptionally stable
- Corrosion resistance
- Resistivity increases during heat treatment

Resistant to Precipitation Hardening
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 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.
