MMCC Copper/Graphite Fiber GC 7-340 Metal Matrix Composite  (discontinued **)
Categories: Metal; Metal Matrix Composite; Nonferrous Metal

Material Notes: Discontinuous graphite fiber copper product primarily used for electronic thermal management applications. Lightweight, high damping, stiffer than aluminum, matched cte, easily machined and plated, superior thermal conductivity, non-carcinogenic.

As power densities increase, reducing or eliminating thermal mismatch strains in an electronic assembly improve system reliability and performance. MMCC’s graphite fiber reinforced aluminum and copper products cover a wide spectrum of substrate and IC packaging requirements.

Data provided by the manufacturer, Metal Matrix Cast Composites (MMCC).
