AlCr2
metal· AlCr2
AlCr2 is an intermetallic compound combining aluminum and chromium, representing a hard, brittle phase that typically forms in aluminum-chromium alloy systems rather than serving as a primary engineering material on its own. This compound is encountered primarily in research and metallurgical contexts as a constituent phase in multi-phase aluminum alloys, where it contributes to strengthening and wear resistance. Its application is indirect—engineers select aluminum-chromium systems (such as certain high-strength or wear-resistant alloys) partly because controlled formation of AlCr2 and related phases improves mechanical properties; it is not commonly specified as a standalone material for critical components.

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.
