CuNi10 Alloy Wire

CuNi10 is a NiCu alloy wire built for stable medium-to-high temp industrial electric heating jobs like ovens, heat treat equipment, and non-stop furnaces.

Standout Features of CuNi10

CuNi10 is a classic engineering tipping point in the NiCu lineup.

• Nickel around 10%
• Resistivity, stability, cost hit the “engineering gold zone”
• Resistance shifts gentler with temp—better control precision

Lots of engineers “get serious with NiCu” starting here.

• Not as copper-heavy as low-nickel
• Cost doesn’t spike like high-nickel

FAQs

Max long-term temp for CuNi10?

Air long-term 350°C, short 400°C. High nickel keeps it steady long-haul.

CuNi10 vs CuNi6—why pick?

CuNi10 → High nickel → Reliable medium-high temp continuous; CuNi6 → Cheaper medium-temp.

Thermal cycles hit CuNi10?

Medium-high nickel handles tons—steady structure, low drift.

OEM custom CuNi10 parts—what?

Coil winding, shaping, pre-fab—into medium-high temp industrial heat treat systems.

Big volume CuNi10 long projects?

Batch trace, composition/resistance checks—long-term bulk consistent.

Precision heating gear?

Super low magnetism—even/steady control in precision setups.
