CuNi6 is a NiCu alloy wire built for stable industrial electric heating jobs like ovens, heat treat equipment, and non-stop furnaces.
Standout Features of CuNi6
CuNi6 is basically an “engineering upgrade” from CuNi2.
- Nickel bumped to around 6%
- Resistivity jumps up (≈ 0.12 μΩ·m)—keeps great heat conduction but allows short-segment or low-power heating.
- Temp coefficient drops noticeably—fits basic power control setups.
- Processes super easy—drawing, welding no hassle—great for cost-watch OEM.
- Nice sweet spot between stability and price
This is the go-to model for lots of medium-low temp industrial gear.
- Steadier than CuNi2
- Cheaper than CuNi10
- Pretty forgiving on design
