· C8 Fe2 Er4

C8Fe2Er4 is an intermetallic compound combining carbon, iron, and erbium (a rare-earth element) in a defined stoichiometric ratio. This is a research-phase material studied primarily for its potential in high-temperature structural applications and magnetic systems where rare-earth strengthening or rare-earth iron magnetic properties are exploited. The erbium addition to iron-carbon systems is unusual in conventional engineering and suggests investigation into specialty high-performance composites, advanced magnetic materials, or extreme-environment structural applications not yet commercialized at scale.

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.
