· YMg2

YMg2 is a rare-earth magnesium intermetallic ceramic compound combining yttrium and magnesium. This material belongs to the family of lightweight intermetallic ceramics being investigated for high-temperature structural applications where low density and thermal stability are critical. YMg2 is primarily found in research and aerospace development contexts rather than mature commercial production, with potential utility in advanced composites and thermal barrier systems where its combination of light weight and ceramic rigidity offers advantages over conventional metallic alloys.

Regulatory Screening

Environmental

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.
