· JVASP-109684· TbPrFe4

TbPrFe4 is an intermetallic compound combining terbium, praseodymium, and iron, representing a rare-earth transition metal alloy. This material belongs to the family of rare-earth iron-based intermetallics, which are typically investigated for magnetic and high-temperature applications where strong magnetic coupling and thermal stability are required. The specific combination of heavy rare earths (Tb, Pr) with iron positions this alloy for potential use in permanent magnets, magnetostrictive devices, and high-temperature magnetic applications where conventional ferromagnets lose performance.

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.
