Be12W
metal· Be12W
Be₁₂W is an intermetallic compound combining beryllium and tungsten, belonging to the family of high-modulus metallic materials studied for structural applications requiring exceptional stiffness and low density. This material is primarily of research and advanced engineering interest rather than high-volume production, valued in aerospace and high-performance applications where the combination of light weight with extremely high elastic moduli offers potential advantages over conventional alloys, particularly in components where deflection must be minimized or where weight savings are critical.

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.
