The progress in high-strength and high-conductivity copper alloy and copper base composites were surveyed.The strengthening mechanism

preparation technology and microstructure and properties of the alloy were introduced.It was pointed out that conventional precipitated strengthening copper alloy possesses higher strength and conductivity and simple preparation technology suitable for manufacturing various electric connecting component

focusing on the comprehensive utilization of strengthening mechanisms and multi-element alloy in future to improve properties and lower cost.Although dispersed strengthening copper has remarkable advantages in elevated application

there exists the problem of complicated technology and un-stable properties.The deformation-processed copper-based composites with high performance can meet the requirements but it is necessary to simplify the process.
