· Al8 Fe4 Er1

Al8Fe4Er1 is an intermetallic compound combining aluminum, iron, and erbium (a rare-earth element), representing a research-phase material in the aluminum-iron-rare-earth alloy family. This composition falls within semiconductor or functional material classifications and is primarily explored in academic and advanced materials development contexts rather than high-volume industrial production. The addition of erbium to aluminum-iron systems is investigated for potential applications requiring specific electronic, magnetic, or thermal properties that differ from conventional Al-Fe binary 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.
