Copper substrates are a type of thin sheets or plates with copper or copper alloys as the core base material. They are fabricated through compounding and processing. The key feature is that they leverage the advantages of copper, such as "high thermal conductivity, high electrical conductivity, and high ductility", to meet the "bearing, conduction, and friction" requirements in various scenarios. They are commonly found in mechanical transmissions (such as clutches), electronic heat dissipation, and industrial manufacturing fields.
