Melting Range of 1320-1370 °C Alloy Bar Material with 7 Strands

Our NiCr alloy bar, with a melting range of 1320-1370°C and a 7-strand configuration, is a hot pick for OEMs who need a material that combines high-temperature performance with flexibility and precision. Likely a nickel-chromium alloy (60-80% nickel, 15-20% chromium, like NiCr 80:20), this bar is engineered to shine in demanding applications where heat, corrosion, and electrical reliability are critical.

The 7-strand design is a standout feature, boosting flexibility and fatigue resistance compared to solid bars. This makes it perfect for applications like flexible heating elements or conductive components that need to bend without breaking, such as in aerospace wiring or industrial furnace coils. With a high resistivity of 1.0-1.5 µΩ·m and a low temperature coefficient of resistance (~100 ppm/°C), it’s a go-to for precision resistors, thermocouples, and heating elements in toasters, ovens, or heavy-duty furnaces. It’s stable up to 1200°C, thanks to a chromium oxide layer that fights off oxidation and corrosion in high-temperature, oxidizing environments (just avoid sulfur-heavy settings).

This alloy’s mechanical properties are just as impressive. With a tensile strength of 600-800 MPa, hardness of 180-220 HV, and 20-30% elongation, it’s tough yet ductile, making it easy to form into custom shapes or wires. The 7-strand structure adds extra durability under dynamic loads, while its weldability ensures seamless integration into OEM designs. Its thermal conductivity (11-17 W/m·K) supports efficient heat dissipation, keeping systems running smoothly.

The nickel-chromium alloy market is growing at a steady 5-6% annually, driven by demand in electrical, aerospace, and industrial sectors. With the rise of energy-efficient heating systems and high-performance electronics, this NiCr bar’s combination of flexibility, resistivity, and heat resistance makes it a top choice. Compared to FeCrAl alloys, it offers better ductility; compared to CuNi44, it handles higher temperatures, making it versatile for extreme conditions.

We produce this NiCr alloy bar with rigorous quality controls to ensure consistent resistivity, strength, and flexibility. The 7-strand configuration is crafted for optimal performance, and we’re equipped to customize it for your specific needs. We’re also exploring sustainable practices, like recycling nickel alloys, to keep our process eco-friendly. While raw material prices can fluctuate, the durability and low maintenance of this alloy make it a cost-effective investment.

In short, our NiCr alloy bar with a 1320-1370°C melting range and 7 strands is your go-to for high-performance applications. Whether you’re building heating elements, resistors, or flexible aerospace components, it delivers the heat resistance, flexibility, and precision you need to make your project a success.
