FeCrAl resistance heating alloy

With the characteristics of high resistance, low temperature coefficient of electric resistance, high operating temperature, good corrosion resistance under high temperature, as well as the lower price, it is widely used in industrial electric furnace, household electrical appliance and far infrared ray device. The material can totally replace Kanthal A-1, Kanthal D, Kanthal AF,etc..
Other Name: Kanthal D, Alloy 815, Alchrome DK, Alferon 901, Resistohm 135,Aluchrom 5, Stablohm 812; Kanthal AF, Resistohm Y, Aluchrom Y, Alloy 837; KanthalA1, Kanthal, Alloy 875, Resistohm 145, Aluchrom 0, Alchrome 875, MWS-875, Stablohm 875
