· JVASP-121513· Ta17Al12

Ta17Al12 is a tantalum-aluminum intermetallic compound that combines the high melting point and corrosion resistance of tantalum with aluminum's lightweight characteristics. This material is primarily of research interest for high-temperature structural applications where extreme thermal stability and chemical inertness are required, though it remains largely experimental and is not widely used in conventional manufacturing.

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.
