· AlNi3

AlNi3 is an intermetallic compound in the aluminum-nickel system, characterized by an ordered crystalline structure that provides exceptional rigidity and thermal stability. This material is primarily of research and specialized industrial interest rather than a commodity alloy, appearing in high-performance applications where its stiffness and high-temperature capability offer advantages over conventional wrought aluminum alloys or nickel superalloys. AlNi3 finds use in aerospace components, thermal management systems, and advanced composites where the combination of relatively light weight with high elastic modulus and narrow operating temperature sensitivity is critical.

Regulatory Screening

Environmental

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.
