· Fe4 Ho2

Fe4Ho2 is an intermetallic compound combining iron and holmium (a rare earth element), classified as a semiconductor with potential magnetic and electronic properties derived from holmium's strong magnetic characteristics. This is a research-stage material rather than an established commercial compound; it belongs to the rare earth-transition metal intermetallic family, which has attracted scientific interest for advanced magnetic, magnetocaloric, and potential magnetoresistive applications. Fe-Ho intermetallics are being investigated in materials science laboratories for next-generation magnetic devices and energy conversion systems, though practical industrial adoption remains limited compared to conventional magnetic alloys.

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.
