Abstract
An object of this invention is to provide a case for rolling powder alloy without failures at the time of rolling. The case for rolling powder alloy (1) is formed like a shape of box and comprises a side constituent member (10) forming like a rectangular frame in a combination of two members (10a, 10a) and surrounding a side surface of metal powder, an upper lid constituent member (11) mounting on one opening of the side constituent member (10) and covering an upper surface of the metal powder, and a lower lid constituent member (12) mounting on the other opening of the side constituent member (10) and covering a lower surface of the metal powder. The peripheral edges of the upper lid constituent member (11) and the lower lid constituent member (12) are, respectively, provided with a peripheral wall (11b, 12b) standing upright along an outer peripheral surface of the side constituent member, and the side constituent member (10) is inserted into a space surrounded by the peripheral wall (11b, 12b). According to such case for rolling powder alloy, the aluminum powder alloy can be easily manufactured without failures at the time of rolling.
