· YCu4

YCu4 is an intermetallic compound in the yttrium–copper system, combining rare-earth and transition-metal elements to form a brittle, hard phase. This material appears in research contexts exploring high-strength, high-temperature phases and rare-earth metallurgy; it is not a widely commercialized engineering alloy. YCu4 and related yttrium-copper phases are of interest in fundamental materials science for understanding intermetallic bonding and crystal chemistry, and in specialized applications where extreme hardness or high-temperature stability may offer advantages over conventional alloys, though brittleness and manufacturing challenges typically limit practical deployment.

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.
