· JVASP-106558· MgCo2Si

MgCo2Si is an intermetallic compound combining magnesium, cobalt, and silicon, belonging to the family of lightweight metallic compounds with potential for high-strength, low-density applications. This is primarily a research-stage material rather than an established commercial alloy; intermetallics in this composition space are investigated for aerospace and automotive contexts where weight reduction and thermal stability are critical. The magnesium base offers inherent lightness while the cobalt-silicon phases aim to improve hardness and creep resistance compared to conventional magnesium alloys.

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.
