· JVASP-112371· Er2Fe17C2

Er₂Fe₁₇C₂ is an intermetallic compound combining erbium, iron, and carbon, belonging to the rare-earth iron carbide family of materials. This is primarily a research-phase material studied for its potential in high-strength, high-temperature applications where rare-earth strengthening of iron-based matrices offers improved performance over conventional steels. Engineers consider this material class when designing components requiring exceptional hardness and thermal stability, though commercial availability and cost typically limit adoption to specialized aerospace, defense, or advanced manufacturing contexts where performance justifies material expense.

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.
