· AlB2

AlB₂ is an aluminum diboride intermetallic compound belonging to the hexagonal metal boride family, characterized by a layered crystal structure that imparts high stiffness and relatively low density. This material is primarily investigated in research and advanced aerospace contexts for lightweight structural applications and composite reinforcement, where its combination of rigidity and low weight offers potential advantages over conventional aluminum alloys, though industrial adoption remains limited and production methods continue to be refined.

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.
