Product Description
Presion Resistance Alloy Constantan/CUNi44 Rod
Constantan( Ualloy049)
(Common Name: CuNi45, NC50.Cuprothal, Alloy 294, Cuprothal 294, Nico, MWS-294, Cupron, Copel, Alloy 45, Neutrology, Advance, CuNi 102, Cu-Ni 44, Konstantan,constantan.)
Ualloy049 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 Ualloy049 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.
Ualloy049 is manufactured from electrolytic copper and pure nickel. In finer wire sizes the alloy is designated as Ualloy049TC(Thermocouple).
Corrosion resistance performance
Style of supply
The thermocouple alloy wires with different varieties and specifications of our company can be applied in all kinds of thermocouples, the temperature ranges from -270ºC to 1800ºC. The thermocouple alloy wires have excellent performance and are extensively used in the temperature measurement and control in different fields, such as metallurgy, chemical industry, petroleum industry, machinery-electric industry, energy industry, agriculture and military industry. Our products conform to the standards of IEC584 -1and IEC-2 and ANSI96-1.
Characteristics:
Excellent thermoelectricity, excellent linear relationship between thermoelectrical potential and the temperature.
Excellent thermoelectrical stability, high accuracy.
Main technical data:
Thermocouple variety, index and temperature measurement range.
