# CuNi2

CuNi2 is a **NiCu alloy wire** built for stable industrial electric heating jobs like ovens, heat treat equipment, and non-stop furnaces.

- High copper, low nickel mix → Moderate resistivity → Awesome for low-power long-haul heating

- Killer oxidation resistance → Steady surface → Longer wire life

- Low magnetism → Better heat evenness → Precise heat treat control

## Standout Features of CuNi2

CuNi2 is the lowest-nickel in NiCu—basically a “copper-heavy” alloy.

- Around 2% nickel—resistivity not crazy high, but way steadier than pure copper.

- Top-notch heat conduction—heats evenly, no hot spots, easy.

- Resistance shifts linearly with temp—control logic straightforward.

Fits great for:

- Low or medium-low temp heating

- Can’t crank power density too high

- In non-stop systems with moderate temps, it’s super tough
