· JVASP-155685· KAl2Si2

KAl2Si2 is an intermetallic compound in the potassium-aluminum-silicon system, representing a research-phase material rather than an established commercial alloy. While this specific stoichiometry is not widely deployed in production, materials in the alkali-metal aluminosilicate family are of interest in lightweight structural applications and ceramic matrix composites, where the combination of low density with moderate strength could reduce component mass. Engineers would consider compounds in this family primarily in academic research contexts or advanced material development programs focused on next-generation lightweight systems, though conventional aluminum alloys and established ceramics remain the dominant choice for most engineering applications due to their proven performance and manufacturing maturity.

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.
