· JVASP-15840· AlCo2Si2

AlCo2Si2 is an intermetallic compound belonging to the aluminum-cobalt-silicon family, a class of ordered metallic materials combining lightweight aluminum with cobalt and silicon for enhanced strength and stiffness. While primarily a research-phase material rather than a commodity alloy, AlCo2Si2 and related ternary intermetallics are investigated for high-temperature structural applications where conventional aluminum alloys lose strength, and where the density advantage over superalloys matters. Engineers consider such materials for weight-critical aerospace or automotive components operating at elevated temperatures, though development focus remains on understanding phase stability, processing routes, and brittleness mitigation.

Export Control

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.
