· O8 Al4 Cu2

O8Al4Cu2 is an intermetallic compound combining aluminum and copper with oxygen, belonging to the semiconductor materials class. This represents an experimental or specialized research composition rather than a widely commercialized alloy; it falls within the family of aluminum-copper oxides and intermetallics that are of interest for advanced applications requiring controlled electronic or thermal properties. The material would be selected where specific phase stability, hardness, or electrical characteristics of the Al-Cu-O system offer advantages over conventional Al-Cu alloys or pure oxides in niche applications.

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.
