Product details
Hangzhou Ualloy Material Co.,Ltd is one of the best copper nickel alloy cuni44 manufacturers and suppliers in China,Website:://.alloystrip.com, welcome to buy discount and low price alloy 294, cuprothal 294, advance, konstantan, constantan from us, and also welcome to check the price and quotation with our factory. CuNi44 (Common Name:CuNi44,NC50.Cuprothal, Alloy 294, Cuprothal 294, Nico, MWS-294, Cupron, Copel, Alloy 45, Neutrology, Advance, CuNi 102, Cu-Ni 44, Konstantan,constantan.) CuNi44 is a copper-nickel alloy (Cu56Ni44 alloy) characterized by high electrical resistance, high ductility and good corrosion resistance. It is suitable for use at temperatures up to 400°C Typical applications for OhmAlloy49 are temperature-stable potentiometers, industrial rheostats and electric motor starter resistances. The combination of negligible temperature coefficient and high resistivity makes the alloy particulary suitable for the winding of precision resistors. CuNi44 is manufactured from electrolytic copper and pure nickel. In finer wire sizes the alloy is designated as CuNi44TC(Thermocouple). Normal composition% Nickel 44 Manganese 1 Copper Bal.
