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),
General Description
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.
Features
1. Higher resistance than copper
2. High tensile strength
3. Good bending proof performance
Application
1. Heating applications
2. Resistance wire
3. Applications with high mechanical requirements

Application of CuNi1
CuNi1 low resistance heating alloy is widely used in low-voltage
circuit breaker, thermal overload relay, and other low-voltage
electrical product. It is one of the key materials of the
low-voltage electrical products. The materials produced by our
company have the characteristics of good resistance consistency and
superior stability. We can supply all kinds of round wire, flat and
sheet materials.
