· FeCrAl

FeCrAl is an iron-chromium-aluminum alloy that combines iron's strength and cost-effectiveness with chromium's corrosion resistance and aluminum's oxidation resistance, forming a protective alumina surface layer at high temperatures. This alloy family is widely used in high-temperature structural and thermal applications where oxidation resistance and mechanical stability are critical, including resistance heating elements, exhaust components, and furnace internals; it is valued over austenitic stainless steels in applications requiring superior oxidation resistance above ~1000°C while maintaining lower material and fabrication costs. FeCrAl alloys are also increasingly explored for nuclear cladding and advanced reactor systems where their resistance to steam oxidation and enhanced accident tolerance offer advantages over conventional zirconium-based cladding.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
