· JVASP-113985· CuBN

CuBN is a copper-boron nitride composite or intermetallic compound that combines the thermal and electrical conductivity of copper with the hardness and thermal stability of boron nitride. This material is primarily investigated for thermal management and high-temperature applications where conventional copper or boron nitride alone cannot meet performance demands, offering potential advantages in demanding aerospace and electronics cooling systems.

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.
