· B2 Fe2 Y1

B2 Fe2Y1 is an intermetallic compound belonging to the iron-yttrium system, classified as a semiconductor material with a B2 (CsCl-type) crystal structure. This is a research-phase compound rather than a commercial material, investigated for its potential in high-temperature structural applications and functional electronic devices where the combination of iron-based metallurgy and rare-earth yttrium offers unique phase stability. The material's interest stems from exploring lightweight, high-strength intermetallics that could serve demanding aerospace and energy applications where conventional superalloys or titanium aluminides may be limited, though development and commercial viability remain at the experimental stage.

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.
