· Si4 Fe2 Tb4

Si₄Fe₂Tb₄ is an intermetallic compound combining iron with terbium (a rare-earth element) and silicon, likely forming a ternary or quaternary phase within the Fe-Tb-Si system. This is primarily a research-stage material rather than an established commercial alloy, investigated for its magnetic and structural properties that arise from the combination of ferromagnetic iron with rare-earth terbium.

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.
