· JVASP-66763· BeTeW

BeTeW is a beryllium-based metal alloy combining beryllium with tellurium and tungsten elements. This is a specialty alloy developed for high-performance applications where extreme stiffness, thermal stability, and density control are critical requirements. The material represents an emerging research composition in the beryllium alloy family, positioned for aerospace, defense, and precision engineering sectors where conventional titanium or aluminum alloys cannot meet simultaneous demands for lightweight design and exceptional rigidity.

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.
