Basic Info
Model No.: CuNi44
Product Description
Model NO.: CuNi44 Material: CuNi Status: Bright Resisivity at 20oc: 0.49 Thermal Conductivity: <-6 Emf Vs Cu: -43 Micrographic Structure: Austenite Trademark: Ualloy Origin: China Product Type: Rod Carbon Content: Low Carbon Max Continuous Service Temperatureoc): 400 Density(G/Cm³): 8.9 Tensile Strength(MPa): ≥420 Approximate Melting Point(Oc): 1280 Magnetic Property: Non Specification: GB/T 6145-1999 HS Code: 74099000 Copper Nickel Alloys(Cupro-nickel)
Principally destined for the manufacturing of low temperatures electric resistances so as heating cables, shunts, resistances for automobile, they have a maximum operating temperature of 752 degrees Fahrenheit.
They do not therefore intervene in the field of resistances for industrial furnaces.
Those are alloys of chemical composition copper + nickel with addition of manganese with a low resistivity (from 231.5 to 23.6 Ohm. Mm2/ft).
The most known, CuNi 44 (also called Constantan) presents the advantage of a very low temperature coefficient.
Their advantages are the following:
Very good resistance to corrosion
Very good malleability
Very good solderability
