Cr20Ni80 Nickel-Chromium Alloy | High Temp Electric Heating Material for Industrial Furnaces – SPARK
High quality Cr20Ni80 alloy is designed for demanding applications that require excellent mechanical properties and corrosion resistance.This advanced material is ideal for use in industries such as aerospace, chemical processing, and high-temperature environments.
Product Introduction
As a signature product of Shougang Gitane, our Cr20Ni80 is specifically designed to operate at continuous temperatures up to 1200°C. Unlike ferritic alloys, Cr20Ni80 maintains excellent malleability and ductility even after long-term use, allowing for easier maintenance and repair of heating elements in industrial furnaces and domestic appliances. Its superior oxidation resistance, coupled with its diamagnetic (non-magnetic) properties, makes it the ideal choice for sensitive aerospace components, chemical processing equipment, and specialized industrial heaters. Whether you are manufacturing metal-sheathed tubular elements, high-end ironing machines, or heavy-duty heat treatment furnaces, SPARK Cr20Ni80 provides the stable thermal performance and morphological stability needed to ensure operational excellence.
