Publication number: 20140321060Abstract: An inexpensive Cu-diamond based composite material having excellent heat conductivity and heat resistance. Conventionally, an infiltration method does not provide a Cu-diamond based composite material having high heat conductivity; an ultrahigh pressure method is expensive; and electric current pressure sintering provides relatively high heat conductivity, a low cost, but insufficient heat resistance. A Cu-diamond based solid phase sintered body contains 2 vol % or more and 6 vol % or less of Cr, and 30 vol % or more and 80 vol % or less of diamond particles containing 20 vol % or more of a high crystallinity diamond component.Type: ApplicationFiled: April 9, 2014Publication date: October 30, 2014Applicant: FUJI DIE CO., LTD.Inventors: Masayuki Ishii, Saki Suzuki, Kozo Kitamura, Kazuhiko Tsuchiya, Minoru Saito, Osamu Terada, Koji Hayashi
