· Al31Cr19

Al31Cr19 is an intermetallic compound in the aluminum-chromium system, characterized by a high chromium content (19 at.%) that significantly alters its phase structure and mechanical behavior compared to conventional aluminum alloys. This material is primarily of research and development interest, studied for potential high-temperature structural applications where improved strength retention and oxidation resistance are needed beyond what binary Al-Cr phases typically offer.

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.
