· Fe8 W4

Fe8W4 is an iron-tungsten intermetallic compound or alloy system combining iron as the primary element with tungsten as a significant alloying addition. This material belongs to the family of refractory metal compounds and is likely studied for high-temperature structural applications where enhanced hardness, wear resistance, and thermal stability are required beyond conventional iron-based 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.
