Iron-chrome aluminium wire
The Iron-chrome aluminium wire high resistance electric heating alloyhas the electronic resistivity high, the resistance temperaturecoefficient is small, the application temperature high characteristic.Under high temperature inoxidizability good, especially suits inincludes in the sulfur and the sulfide atmosphere uses, also the priceis inexpensive, is the industry electric stove, the domestic electricappliances, in the far infrared installment ideal gives off heat thematerial.
Hard chromium aluminum electric heating alloy silk main technical performance:
