Nickel Chromium Wire

The hard chromium chromium high resistance electric heating alloy has the electronic resistivity high, the resistance temperature coefficient is small, the application temperature high characteristic.Under high temperature oxidizability good, especially suits includes in the sulfur and the sulfide atmosphere uses, also has the proportion lightly, the surface shoulders, the service life high long,the price is low and so on a series of merits, is the industryelectric stove, the domestic electric appliances, in the far infrared installment ideal gives off heat the material.
