· JVASP-75023· BeCuTe

BeCuTe is a beryllium-copper-tellurium alloy that combines the high strength and electrical conductivity of beryllium-copper base systems with tellurium additions for enhanced properties. This material is used in specialized applications where a combination of mechanical strength, thermal conductivity, and electrical performance is required, particularly in aerospace and electronics industries where weight reduction and reliable performance under thermal cycling 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.
