· JVASP-141333· Zn9Fe4

Zn9Fe4 is an intermetallic compound in the zinc-iron system, representing a specific stoichiometric phase that forms in zinc-iron alloys. This material is primarily of research interest in metallurgy and materials science, as it represents one of the equilibrium phases in the Zn-Fe phase diagram; industrial zinc-iron alloys typically target different compositions for galvanizing, coating, or wear-resistant applications. Engineers studying zinc-iron systems may investigate Zn9Fe4 to understand phase formation, mechanical behavior during thermal cycling, or as a constituent phase in composite or gradient coating systems where controlled microstructure is critical.

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.
