· Al2 N2

Aluminum nitride (AlN) is a ceramic semiconductor compound belonging to the III-V nitride family, valued for its combination of wide bandgap properties and excellent thermal conductivity. It is primarily used in high-power electronics, RF (radio frequency) devices, and thermal management applications where heat dissipation and electrical insulation are critical, as well as in optoelectronics for UV-emitting devices. AlN's appeal over competing wide-bandgap semiconductors lies in its superior thermal performance and relative cost-effectiveness for certain applications, though it faces competition from GaN (gallium nitride) in some power electronics markets.

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.
