ALUMINUM COMPOSITE BODY MATERIAL INCLUDING METAL AND/OR CERAMIC GRAPHITE, AND PRODUCTION METHOD OF ALUMINUM COMPOSITE BODY MATERIAL INCLUDING METAL AND/OR CERAMIC GRAPHITE
To provide an aluminum composite body material including metal and/or ceramic graphite in which a carbon graphite-based material and an aluminum material are combined, and which achieves high strength, high heat conductivity and low thermal expansion and can be widely applied in an industrial field, and a technique for providing the same material.SOLUTION: An aluminum composite body material including metal and/or ceramic graphite is configured so that, a molded body being formed of a material obtained by adding a silica-based binder to an outside of mixture powder formed of graphite powder which is not amorphous and any of metal powder and/or ceramic powder, is combined with molten metal of aluminum metal or an aluminum alloy, the aluminum composite body material has flexure strength of 90 MPa or more, heat conductivity in any of an XY-direction and a Z-direction is 240 W/m K or more, and in addition, a thermal expansion coefficient in any of the XY-direction and the Z-direction is 6.0 ppm/K or lower.SELECTED DRAWING: None
【課題】カーボングラファイト系材料とアルミニウム材料とを複合化させた、高強度、高熱伝導度及び低熱膨張率を併せ持つ、工業上広く利用することが可能な金属及び／又はセラミックス・グラファイト含有アルミニウム複合体材料の実現と、該材料の提供技術の開発。【解決手段】非晶質でないグラファイト粉末と、金属粉末及び／又はセラミックス粉末のいずれかを含む混合粉末の外側にシリカ系のバインダーが添加された材料からなる成型体が、アルミニウム金属又はアルミニウム合金の溶湯で複合化されてなり、その曲げ強度が９０ＭＰａ以上であり、且つ、ＸＹ方向又はＺ方向のいずれかの熱伝導率が２４０Ｗ／ｍ・Ｋ以上であり、更に、ＸＹ方向又はＺ方向のいずれかの熱膨張係数が６．０ｐｐｍ／Ｋ以下である金属及び／又はセラミックス・グラファイト含有アルミニウム複合体材料及び該複合体材料の製造方法。【選択図】なし
