Product Description
Cr10Ni90 Nichrome flat wire is composed of approximately 10% chromium and 90% nickel, delivering an optimal balance of high electrical resistance, ductility, and exceptional heat tolerance. This wire maintains stable performance under prolonged high-temperature operations, making it ideal for furnace and heater applications.
The bright annealed processing results in a smooth, oxide-free surface suitable for precision coil winding and flat element formation. With excellent thermal stability and extended service life, Furnace Grade Nichrome Cr10Ni90 wire is widely used in industrial, commercial, and laboratory heating systems.
