· LiAl3

LiAl3 is an intermetallic compound combining lithium and aluminum, belonging to the family of lightweight metallic intermetallics. This material is primarily of research and development interest rather than a mainstream engineering alloy, valued for its extremely low density combined with moderate stiffness, making it attractive for weight-critical aerospace and automotive applications where conventional aluminum alloys or titanium would be too heavy.

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.
