Non magnetic Copper Nickel Alloy Strip Gold / Silver Color Good Wear Reaiatance
Description
Material: CuNi1, CuNi2, CuNi6, CuNi8, CuNi10, CuNi14, CuNi19,
CuNi23, CuNi30, CuNi34, CuNi44 in form of strip/heet/plate/falt
wire/ribbon
As a big manufacturer and exporter in China on the line of electric
resistance alloy, we can supply all kinds of electric resistance
alloy wire and strips (resistance steel wire and strips),
Advantage
Due to has high tensile strength and increased resistivity values,
TANKII copper nickel alloy wires are the first choice for
applications as resistance wires. With the different nickel amount
in this product range, the characteristics of the wire can be
chosen according to your requirements. Copper nickel alloy wires
are available as bare wire, or enamelled wire with any insulation
and self-bonding enamel. Furthermore, litz wire made of enamelled
copper nickel alloy wire are available.
Application
Copper-nickel alloy contains specific minor amounts of additional elements to achieve precise values for the temperature coefficient of resistivity. Careful control of melting and conversion practices results in a very low level of pinholes at ultra-thin thicknesses. The alloy is used extensively for foil resistors and strain gauges.
