ErFeB4
metal· JVASP-137615· ErFeB4
ErFeB4 is an intermetallic compound composed of erbium, iron, and boron, belonging to the rare-earth iron boride family of materials. This material is primarily of research interest rather than established industrial production, investigated for its potential magnetic and high-temperature properties inherent to rare-earth iron compounds. Engineers would consider this material for advanced applications requiring rare-earth strengthening or specialized magnetic behavior, though it remains in the developmental phase with limited commercial availability compared to conventional rare-earth permanent magnets or structural alloys.

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.
