· JVASP-153194· TbAl8Cr4

TbAl8Cr4 is an intermetallic compound combining terbium, aluminum, and chromium, representing a rare-earth metal system typically studied for high-temperature structural applications and magnetic properties. This material belongs to the family of rare-earth aluminum-transition metal compounds, which are primarily pursued in research contexts for potential use in aerospace, automotive, and energy conversion systems where thermal stability and lightweight characteristics are valued. The incorporation of terbium and chromium into an aluminum matrix creates a system with potential for enhanced hardness and creep resistance compared to conventional aluminum alloys, though commercial deployment remains limited and the material is better characterized as an emerging intermetallic rather than an established engineering alloy.

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.
