BeCuW2
metal· JVASP-68059· BeCuW2
BeCuW2 is a beryllium-copper-tungsten composite or alloy combining the high strength and thermal conductivity of beryllium and copper with the density and refractory properties of tungsten. This material is typically encountered in specialized aerospace, defense, and high-performance electronics applications where the combination of low weight, excellent thermal management, and mechanical rigidity is critical, though it remains less common than conventional beryllium-copper alloys due to processing complexity and cost.

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.
