0Cr25Al5 FeCrAl Alloy
FeCrAl alloy materials are resistant to creep over a wide range of temperatures. Fecral 255 alloy have several advantages such as lower raw material cost, superior oxidation resistance, lower density, and lower coefficient of thermal expansion than nicr alloys.
Product Description
FeCrAl alloy materials are resistant to creep over a wide range of temperatures. Fecral 255 alloy have several advantages such as lower raw material cost, superior oxidation resistance, lower density, and lower coefficient of thermal expansion than nicr alloys. However, fecral wire has lower strength than nicr alloys, after heating, the ductility of the alloy becomes poor, easy brittleness, not easy to weld.
0Cr25Al5 resistance alloy is composed of iron chromium aluminum, which has high resistivity, low temperature coeffcient of electric resistance,high working temperature, good oxidation resistance at high temperature, and the maximum applicable temperature is as high as 1250 degrees.
ocr25al5 is mainly used in the production of ceramic electric cooking utensils, industrial furnaces, and various electric heating elements.We mainly produce ocr25al5 alloy heating wire,fecral 25/5 strip,0cr25al5 fecral alloy foil,fecral heating resistance ribbon,fecral wire mesh,etc.
