· Al4 Ho2

Al₄Ho₂ is an intermetallic compound combining aluminum with holmium (a rare-earth element), classified as a semiconductor material. This is a research-stage compound rather than a commercialized engineering material; it belongs to the family of rare-earth aluminum intermetallics being investigated for potential applications in advanced electronic and magnetic devices. The incorporation of holmium—a lanthanide with strong magnetic properties—suggests potential utility in specialized applications requiring combined electrical and magnetic functionality, though industrial adoption remains limited pending further development and characterization.

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.
