· JVASP-97778· Y3FeB7

Y3FeB7 is an iron-yttrium boride intermetallic compound that combines rare-earth and transition-metal elements to achieve high hardness and thermal stability. This material is primarily investigated in research contexts for hard coatings, wear-resistant applications, and high-temperature structural components, where the yttrium addition enhances oxidation resistance compared to conventional iron borides. Engineers would select this material family when extreme hardness and thermal performance are required in environments where traditional steels or tungsten carbides may degrade.

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.
