Nichrome wire, Nickel-Chrome wire, strip and bar

NICKEL-CHROMIUM ALLOY WIRE

Nickel-Chromium and Nickel-Chromium-Iron resistance wires have a series of advantages. They can withstand high temperatures and has good stability at high temperatures, making it suitable for use in high-temperature environments.They have good oxidation resistance and can maintain their electrical conductivity and resistance value in an oxidizing atmosphere.They have high resistance accuracy, which can meet the requirements of precise resistance measurement and control.Nickel-chromium resistance wires haave a long service life and can work reliably for a long time under normal use conditions.They have certain mechanical strength and can withstand certain external forces and vibrations. Nickel-chromium resistance wires can be used in various fields, such as electric heating elements, industrial furnaces, and temperature sensors. Our company has full ranges of Cr20Ni80, Cr15Ni60, Cr30Ni70, Cr20Ni30 and Cr20Ni35 wires, strips and strand wires. They are the first choose to manufacture the high quantity heating elements..
