· JVASP-118169· Al2As

Al2As is an intermetallic compound combining aluminum and arsenic, belonging to the III-V semiconductor material family. While not commonly used in traditional structural or functional applications, Al2As and related aluminum-arsenide compounds are primarily of research interest for optoelectronic and semiconductor device development, particularly in heterostructure applications where lattice matching and bandgap engineering are critical. Engineers and researchers investigating advanced semiconductor devices, photovoltaic systems, or compound semiconductor epitaxy may encounter this material as a constituent phase or potential candidate material, though commercial availability and maturity remain limited compared to established III-V alternatives.

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.
