Cr10Ni90 resistance wire is a premium nickel-chromium alloy engineered for precision heating applications requiring exceptional thermal stability, low electrical drift, and resistance to oxidation in extreme environments. With a composition of 89–91% nickel, 9–11% chromium, and trace elements (≤0.5% iron, ≤0.3% manganese), this alloy delivers unmatched performance at temperatures up to 1,300°C (2,372°F). Its ultra-low temperature coefficient of resistance (TCR ≤ 50×10⁻⁶/°C) ensures minimal electrical variance under thermal cycling, making it indispensable for aerospace sensors, nuclear reactor instrumentation, and semiconductor manufacturing equipment.
Certified to ASTM B344 and IEC 60172 standards, Cr10Ni90 wire achieves a tensile strength of 600–800 MPa and elongation ≥25%, outperforming conventional Ni-Cr alloys in high-vacuum and inert gas environments. With an electrical resistivity of 1.04 µΩ·m and near-zero magnetic permeability, it guarantees precision in sensitive applications such as cryogenic systems, medical imaging devices, and high-frequency induction heating.
