Corrosion-Resistant NiCr Alloy with High Thermal Conductivity and Precision Electrical Properties

Our corrosion-resistant NiCr alloy, with high thermal conductivity and precision electrical properties, is a powerhouse for manufacturers who need materials that can take the heat—literally and figuratively. Typically composed of 60-80% nickel and 15-20% chromium, this alloy is engineered for demanding applications where reliability, heat dissipation, and electrical precision are non-negotiable.

What sets this NiCr alloy apart? Its high resistivity—around 1.0-1.5 µΩ·m—paired with a low temperature coefficient of resistance (TCR) makes it a rockstar for precision resistors and heating elements. Whether it’s in toasters, industrial furnaces, or high-value rheostats, this alloy delivers consistent electrical performance even when temperatures climb. Speaking of heat, it’s stable up to 1200°C, thanks to a robust chromium oxide layer that protects against oxidation and corrosion in harsh, high-temperature environments.

The thermal conductivity, ranging from 11-17 W/(m·K), is another big win. While it’s not as high as copper, it’s plenty effective for dissipating heat in heating elements, thermocouples, and aerospace turbine components, ensuring systems stay efficient without overheating. Plus, its corrosion resistance is top-notch, especially in oxidizing conditions, making it a go-to for industrial settings where chemical exposure is a concern. Just keep it away from sulfur-heavy atmospheres, where it’s less effective.

Manufacturers love how easy this alloy is to work with. Its good ductility and weldability mean we can form it into wires, strips, or custom shapes without a hassle, perfect for everything from fine thermocouple wires to heavy-duty furnace elements. With a tensile strength of 600-800 MPa and hardness of 180-220 HV, it’s tough enough to handle mechanical stress while staying pliable for precision work.

The nickel-chromium alloy market is thriving, with a growth rate of about 5-6% annually, driven by demand in electrical, aerospace, and automotive sectors. As industries push for more efficient heating systems and reliable electronics, our NiCr alloy’s combination of corrosion resistance, thermal conductivity, and electrical precision makes it a standout. Compared to CuNi 44, it offers higher temperature resistance, and versus FeCrAl alloys, it provides better ductility and corrosion resistance in oxidizing conditions.

We produce this NiCr alloy with rigorous quality controls to ensure consistent resistivity, strength, and surface quality. We’re also committed to sustainability, exploring recycling options to keep our process eco-friendly. While nickel prices can fluctuate, the long lifespan and low maintenance of this alloy make it a cost-effective choice for high-performance applications.

In a nutshell, our NiCr alloy with high thermal conductivity and precision electrical properties is your trusted partner for tackling tough projects. From heating elements to thermocouples, it delivers the durability, efficiency, and reliability you need to keep things running smoothly. Ready to power up your manufacturing?
