· Al5FeNi4

Al5FeNi4 is an intermetallic compound belonging to the aluminum-iron-nickel family, characterized by a fixed stoichiometric composition that creates an ordered crystal structure distinct from conventional solid-solution alloys. This material is primarily of research and specialty applications interest, valued in high-temperature and wear-resistant contexts where its intermetallic nature provides strength and hardness at elevated temperatures, though it typically exhibits lower ductility than conventional aluminum alloys. The Al-Fe-Ni system has attracted attention in aerospace and thermal barrier applications, and as a reinforcing phase in composite materials, where its ordered structure and thermal stability offer advantages over softer aluminum-based alternatives.

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.
