· AlNi

AlNi is an intermetallic compound formed from aluminum and nickel, belonging to the family of ordered metallic phases with well-defined crystal structures. These materials are typically used in high-temperature applications and specialty alloys where enhanced strength and oxidation resistance are required beyond conventional aluminum or nickel alloys.

Export Control

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.
