Nichrome Cr15Ni60 High Temperature Resistance Wire 1150°C Oxidation Resistance

Nichrome Cr15Ni60 High-Temperature Resistance Wire | 1150°C Oxidation Resistance & Longevity

Description

Nichrome Cr15Ni60 resistance wire offers superior thermal stability (up to 1150°C), corrosion resistance, and compliance with global standards. Ideal for industrial heating, automotive, and electronics.

Product Overview

Nichrome Cr15Ni60 resistance wire is a nickel-chromium alloy engineered for high-temperature applications requiring durability and consistent electrical performance. Comprising 15–18% chromium (Cr) and 55–60% nickel (Ni), this alloy forms a protective chromium oxide (Cr₂O₃) layer at elevated temperatures, ensuring resistance to oxidation, sulfurization, and carburization. With a maximum operating temperature of 1150°C in oxidizing atmospheres and 950°C in reducing environments, it outperforms lower-grade alloys in industrial furnaces, automotive sensors, and consumer appliances.

The alloy’s balanced electrical resistivity (1.12–1.18 μΩ·m at 20°C) ensures stable heat generation, while its mechanical strength (≥600 MPa tensile strength) and ductility (≥25% elongation) allow for seamless shaping into coils, heating elements, and precision components. Compliant with ASTM B344, GB/T 1234-2012, and IEC 60216, Nichrome Cr15Ni60 is globally trusted in Southeast Asian electronics manufacturing, Middle Eastern petrochemical plants, and European aerospace systems. Its low thermal expansion coefficient (14×10⁻⁶/°C) minimizes deformation under cyclic heating, enhancing lifespan in demanding applications.
