· Al71Co25Ni4

Al71Co25Ni4 is an intermetallic compound in the aluminum-cobalt-nickel system, representing a research-phase material rather than an established commercial alloy. This composition sits within the broader family of high-entropy and intermetallic materials being investigated for elevated-temperature applications where conventional aluminum alloys reach their performance limits. The material is primarily of academic and exploratory interest, with potential applications in aerospace and high-temperature structural components if suitable processing and property combinations can be achieved.

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.
