· Y3Al2

Y3Al2 is an intermetallic compound belonging to the yttrium-aluminum system, a class of ordered metallic materials that combine rare-earth and light-metal elements. While primarily a research and development material rather than a commodity alloy, Y3Al2 and related yttrium aluminides are investigated for high-temperature structural applications where lightweight properties and thermal stability are critical, particularly in aerospace and advanced energy systems where conventional superalloys reach their performance limits.

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.
