Products Description
FeCrAl strip is an important type of high-temperature alloy material, which includes a series of different grades of alloy strips, such as 1Cr13Al4, 0Cr15Al5, 0Cr19Al3, 0Cr21Al4, 0Cr21Al6, 0Cr23Al5, 0Cr25Al5, 0Cr21Al6Nb, etc. These alloy strips have slight differences in parameters and composition, but they are mainly composed of iron (Fe), chromium (Cr), and aluminum (Al), with different contents of Cr and Al. These alloy strips have high electrical resistivity, good high-temperature stability, and oxidation resistance, and can maintain stable performance in high-temperature environments. They are widely used in heat treatment furnaces, industrial heating equipment, household appliances, and other fields as heating elements, which can provide stable and efficient heating effects.
