NiCr (nickel-chromium) resistance cable is a high-quality material designed for electric heating applications that require reliable performance at temperatures up to 1200°C. Thanks to its excellent resistance to oxidation and its durability against frequent changes or wide thermal fluctuations, this cable is ideal for both domestic and industrial uses.
Made of a nickel-chromium alloy, NiCr cable offers high electrical stability, great plasticity and a long service life even under extreme conditions. It is widely used in industrial electric furnaces, heating apparatus, control resistors, far-infrared devices and other high-performance electric heating systems. NiCr resistance wire is the ideal choice for those looking for efficiency, durability, and superior thermal performance in their electric heating applications.
