0Cr24Al6Re

0Cr24Al6Re is a ferric iron-chromium-aluminium(FeCrAl) high resistance heating alloy for using at temperature up to 1400℃. This alloy is almost equal to Kanthal@APM, and in China we 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.
