FAQ
Cr10Ni90 is a high-nickel (90% Ni, 10% Cr) resistance alloy wire prized for its purity, ductility, and performance in heating applications. It belongs to the Nichrome family but offers higher nickel content for enhanced properties.
Cr10Ni90 provides better ductility and slightly different resistivity/oxidation characteristics, making it suitable for applications needing higher nickel content and formability, while Cr20Ni80 is more common for general high-temp use.
We supply Cr10Ni90 Nichrome wire in a wide range of diameters (e.g., 0.1mm to several mm) and lengths. Contact us for custom specifications.
It supports continuous operation up to approximately 1200°C depending on conditions, with a melting point around 1427°C.
