· Lu1 Ta1 Ru2

Lu₁Ta₁Ru₂ is an intermetallic compound combining lutetium, tantalum, and ruthenium—a research-phase material in the family of refractory metal intermetallics. This composition falls within the broader class of high-entropy and multi-principal-element alloys being investigated for extreme-environment applications where conventional superalloys reach their limits. The material is not yet established in mainstream commercial production; it represents exploratory work in materials for next-generation aerospace propulsion, nuclear systems, or high-temperature structural applications where oxidation resistance, creep resistance, and phase stability at elevated temperatures are critical.

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.
