BaAlSi
metal· BaAlSi
BaAlSi is an intermetallic compound combining barium, aluminum, and silicon, belonging to the class of lightweight metallic materials with ceramic-like properties. This material is primarily of research and development interest for advanced applications requiring combinations of low density with moderate stiffness, though industrial adoption remains limited compared to established aluminum or magnesium alloys. The barium-containing composition makes it potentially valuable for applications where specific thermal, electrical, or radiation-shielding characteristics are beneficial, though practical engineering use cases and production maturity are not yet widespread.

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.
