· JVASP-70763· LaZr2Be

LaZr2Be is an experimental intermetallic compound combining lanthanum, zirconium, and beryllium—a research-phase material rather than an established engineering alloy. This composition sits within the broader family of rare-earth–refractory metal intermetallics, which are investigated for high-temperature structural applications where conventional superalloys reach their limits. The beryllium addition is notable for its potential to reduce weight while the zirconium and lanthanum combination targets thermal stability and oxidation resistance; however, beryllium's toxicity in powder form and the material's lack of established processing routes currently limit industrial deployment.

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.
