Ohmalloy KT-A Similarity Fecral Heating Resistance Wire/Strip for
Heating Elements Industrial Furnaces
OHM-142C (Common Name: 0Cr23Al6, A1, )
OHM-142C is a iron-chromium-aluminium alloy (FeCrAl alloy)
characterized by high resistance, low coefficient of electric
resistance, high operating temperature, good corrosion resistance
under high temperature.It is suitable for use at temperatures up to
1400°C.
Typical applications for OHM-142C are used in home appliances and
industrial furnace,and kinds of elements in heaters and dryers
which is similar to A1 application.
