ScAlN2
metal· JVASP-100444· ScAlN2
ScAlN2 is a scandium aluminum nitride compound, a quaternary ceramic material that combines the hardness and thermal stability of nitride ceramics with the lightweight properties of aluminum-based systems. This material is primarily of research and development interest, representing work in advanced ceramic coatings and structural materials where enhanced mechanical performance and thermal resistance are required at elevated temperatures. ScAlN2 is notable within the nitride ceramic family for its potential to offer improved properties over binary AlN or traditional TiN/CrN coatings, making it relevant for applications demanding both durability and thermal management in harsh environments.

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.
