KBe2W
metal· JVASP-71226· KBe2W
KBe2W is an intermetallic compound combining potassium, beryllium, and tungsten elements, representing an experimental material in the lightweight high-density metal family. While not yet established in mainstream industrial production, this composition is of research interest for applications requiring unusual combinations of low atomic mass (beryllium) with high-density refractory properties (tungsten), potentially useful in specialized aerospace, nuclear, or shielding applications where density and thermal stability must be balanced with weight constraints.

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.
