· JVASP-69639· Mg4BeMo

Mg4BeMo is a quaternary magnesium-based alloy containing beryllium and molybdenum additions, belonging to the family of lightweight metallic materials designed for high-performance structural applications. This alloy combines magnesium's inherent low density with beryllium's strengthening effects and molybdenum's contribution to elevated-temperature stability and hardness, though it remains primarily a research and specialized-use material rather than a commodity engineering alloy. Industrial adoption is limited due to beryllium's toxicity concerns and processing challenges, but the alloy family represents an important exploration pathway for ultra-lightweight systems where conventional magnesium alloys or aluminum alternatives fall short on strength-to-weight or thermal performance criteria.

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.
