AlGr
AlGr is a high-heat-conductivity composite material based on aluminum alloy matrix and a filler of high-modulus ground graphite fiber or ground natural graphite. The method of producing the material is the impregnation of a powder preform with liquid metal. The material has a high thermal conductivity and low density and can be used for effective solve problems related to the heat sink.
