· JVASP-74828· MgBe2Co

MgBe₂Co is an intermetallic compound combining magnesium, beryllium, and cobalt—a research-phase material in the broader family of lightweight, high-stiffness intermetallics. This ternary system represents an experimental approach to achieving favorable combinations of low density with significant elastic rigidity, potentially useful in weight-critical aerospace and defense applications where stiffness-to-weight ratio is paramount. However, as a non-commercial compound, processing challenges, beryllium toxicity concerns, and limited availability restrict its current use to laboratory investigations and specialized high-performance development programs rather than mainstream industrial production.

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.
