Manufacture and sales of ultra-fine resistance wires such as nichrome wires (nickel-chromium alloy wires) and iron-nickel alloy wires Tokyo Resistance Wire Co.

CN30 (CuNi23) Copper Nickel Resistance Wire Type 30

Code:CN30 (Copper Nickel Resistance Wire Type 30)

Properties and Applications

Heat-resistant, oxidation-resistant, and can be used up to 300°C. Non-magnetic and slightly less workable than Type 49. Used for low-temperature heating elements, heaters for circuit breakers, and other medium-resistance resistance materials.
