· JVASP-125820· K3Al

K3Al is an intermetallic compound in the potassium-aluminum system, representing a research-phase material rather than an established commercial alloy. While the potassium-aluminum family is primarily of academic interest, compounds in this system are investigated for lightweight structural applications and potential use in specialized chemical or thermal management contexts where ultra-low density combined with specific intermetallic properties may be relevant.

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.
