Project Description

0Cr24Al6RE

0Cr24Al6RE is a ferric FeCrAl high resistance heating alloy for using at temperature up to 1400℃. This alloy is almost equal to Kanthal APM, and in China called it HRE. HRE is mostly made into resistance heating wire/ribbon used in the high temperature furnace. The alloy is characterized by high resistivity and very good oxidation resistance.
