Be4CrMo
metal· JVASP-120539· Be4CrMo
Be4CrMo is a beryllium-based alloy containing chromium and molybdenum, belonging to the family of lightweight metallic materials that leverage beryllium's exceptional strength-to-weight ratio. This material is primarily explored in aerospace and defense applications where weight reduction is critical, particularly in components requiring high stiffness and thermal stability. The chromium and molybdenum additions enhance hardness, corrosion resistance, and high-temperature performance compared to pure beryllium, making it suitable for structural elements where conventional aluminum or titanium alloys would be too heavy.

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.
