Product Description

Cuni Alloy Flat Wire"

We are the only manufacturer which gathers electrical heating alloy wire & strip and heating cable in China.
So no matter you need alloy bare wires or heating wires with any insulation, we can produce for you.
The Cuni alloy wire can be round and flat. The diameter and resistance are customized.

We produce CuNi1, CuNi2, CuNi6, CuNi8,CuMn3, CuNi10, CuNi14, CuNi19, CuNi22, CuNi23, CuNi30, CuNi34, CuNi40, CuNi44.  As known, CuNi 44 (also called Constantan) presents the advantage of a very low temperature coefficient.
