· Al3Ni2

Al3Ni2 is an intermetallic compound in the aluminum-nickel system, forming a hard, brittle phase that appears in cast aluminum-nickel alloys and high-temperature composites. This material is primarily of research and specialized industrial interest rather than a primary structural phase, valued for its contribution to strengthening mechanisms in nickel-containing aluminum alloys and for potential high-temperature applications where intermetallic phases provide enhanced stiffness and creep resistance. Engineers encounter Al3Ni2 as a constituent phase in advanced aluminum casting alloys and precipitation-hardened systems, where understanding its presence is critical for predicting material behavior, though direct use of pure Al3Ni2 remains limited to experimental aerospace and thermal management applications.

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.
