· Al3Ni

Al3Ni is an intermetallic compound combining aluminum and nickel, belonging to the family of lightweight metallic intermetallics that offer high strength-to-weight ratios. While primarily a research and development material rather than a mainstream engineering product, Al3Ni is studied for high-temperature applications where conventional aluminum alloys lose strength, particularly in aerospace and automotive contexts seeking weight reduction without sacrificing performance at elevated temperatures.

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.
