Abstract: A sink compound laminate molding process having a copper material in thickness of 0.1-0.8 mm placed at the bottom of the molding cavity with the bottom of the copper laminate fully bound to the bottom of the molding cavity, the copper being heated up to 300-600° C., and molten aluminum being filled into the molding cavity using a gravity casing process to create diffusion bonding to the interface between the copper and aluminum materials, molten aluminum being cooled and cured to avail an integrated compound laminate in a given profile of heterogeneous copper and aluminum.

Abstract: A sink compound laminate modeling process having a copper material in thickness of 0.1˜0.8 mm placed at the bottom of the modeling cavity with the bottom of the copper laminate fully bound to the bottom of the modeling cavity, the copper being heated up to 300˜650° C., and melting aluminum being filled into the modeling cavity using gravity casing process to create diffused lamination to the interface between the copper and aluminum materials, melting aluminum being cooled and cured to avail an integrated compound laminate in a given profile of heterogeneous copper and aluminum.

Abstract: The present invention of a structure and manufacture of a heat sink with high heat transmission mainly uses a shear stress caused by stirring to break or crush the solidified arborescent primary crystal at a solid/liquid two-phase area of a aluminum alloy to form a slag fluid with ball-filled solid crushed grit; then ceramic grains are added in and dispersed by the solid grains scattered in the liquid-phase metal; through continuous stirring, the aluminum alloy becomes a fine mixed fluid of ceramic and aluminum alloy without arborescent forms; finally, the external configuration of a heat sink is accomplished through directly compression casting by using the special nature of the aluminum alloy to mold the entire heat sink and to enhance the effect of heat dissipation of the heat sink of the same structure through the high heat transmission efficiency of the ceramic grains.

Abstract: The present invention provides a highly heat dissipative and abrasion resistant bicycle brake disk. The brake disk is of a metal-based composite material, wherein the metal-based composite material includes a metal-containing material and 5% to 40% by volume of ceramic particles.
