· Al3 Ta1

Al3Ta1 is an intermetallic compound belonging to the aluminum-tantalum system, classified as a semiconductor material. This compound represents a research-phase material within the family of refractory intermetallics, which are being investigated for high-temperature structural and functional applications where conventional alloys reach their performance limits. Al3Ta intermetallics are of interest in aerospace and materials research contexts for their potential combination of low density (aluminum-based) with the thermal stability and strength contributions of tantalum, though industrial adoption remains limited and the material is primarily studied in academic and advanced development settings.

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.
