The metal - graphite composite material and its production method of possessing temperature conductivity

摘要

This invention is ideal in 2 dimensional spread of heat, the metal - graphite composite material and its production method of possessing temperature conductivity in two axial direction are offered. The metal - graphite composite material of this invention, 20 - 80 volume % the scaly graphite powder and the copper and the aluminum or includes with the matrix which is selected from the group which consists of those alloys, the scaly graphite powder where normal vector of the scaly aspect above the 20 tilts vis-a-vis the normal vector of the conduction of heat easy aspect of the metal - graphite composite material is 15% or less vis-a-vis scaly graphite powder the whole description above, the metal - graphite composite material features that it possesses the relative density of 95% or more.
