Next, the microspheres 2 having the aluminum coating 3 formed thereon are mixed in a volume ratio of 20% into an aluminum-5% magnesium base powder having a predetermined particle size, and are stirred so as to be uniformly dispersed. Next, the mixture of the base material 1 and the microspheres 2 is heated to a predetermined temperature (in this example, 62011 to 630 degrees Celsius) at which a part of the mixture softens and the rest remains in an assimilated state, so that it becomes fluid. shall be. By utilizing the difference in melting point of the two constituents of the mixture, the liquid or near-liquid part and the solid part are mixed in an appropriate ratio to form a fluidized state. Then, this fluid mixture is cast and solidified to obtain an aluminum-microsphere composite billet. Thereafter, the billet is heated again to the predetermined temperature as required, and subjected to various forming processes such as rolling, extrusion, IR molding, and casting, as well as heat treatments such as quenching and annealing, to obtain a final product.

とができる。As mentioned above, when heating and fluidizing the mixture of base material 1 and microspheres-2, the reason why the heating temperature is limited to iIf that provides a suitable solid phase ratio is that if the ratio of the fluidized portion is large, the mixture On the other hand, since the specific gravity of the base powder and the microspheres is significantly different, if the entire mixture becomes liquid, the two will be separated by the difference in specific gravity and the desired microsphere distribution state will be achieved. In addition, if the proportion of the fluidized portion becomes too small, the mixture will not be sufficiently complexed. After the in-phase ratio is predetermined, preferably the solid phase ratio of the microspheres 2 is 100% and the fluidization ratio of the base material 1 is 30 to 70%.
When heated to such a temperature, it is possible to promote the formation of a composite between the base powder and the microspheres while preventing their separation, and also to impart fluidity to the mixture, resulting in good moldability.

は混合物の成形性を向上できる。Now, the microspheres 2 dispersed in the base material 1 are weak and easily destroyed by unidirectional external force by themselves, but once they are mixed into the base material 1, their outer shape becomes spherical. Therefore, the external forces applied thereto are balanced with each other, and the microspheres 2 become extremely stable against external forces. Furthermore,
Since the internal gas expands and contracts in accordance with the thermal expansion and contraction of the base material 1, thermal stability is also high. Moreover, a coating is formed on the surface of the microsphere-2 to strengthen it, and in combination with the above-mentioned properties, the microsphere-2 has the following properties:
It is stable even in various molding processes such as manufacturing the above-mentioned composite billet, and can withstand a surface pressure of, for example, 100 ko/cm2 or more, and will not be broken within the base material 1. As in this embodiment, when the same or similar physical properties to the base material 1 are used as the coating material, the wettability of both materials and the moldability of the mixture can be particularly improved.
