Claim Text:
1. A method for manufacturing a boron-containing aluminum plate material, the method comprising: spreading boron-containing alloy particles comprising borate particles having a boron content of 5 mass % or more in a layer shape over a bottom plate of aluminum or aluminum alloy placed in a container; after the spreading, mounting a tundish on a top of the container and preheating the container and the tundish together at 300° C. to 500° C.; enveloped-casting the layer of the boron-containing alloy particles in the preheated container with molten aluminum or molten aluminum alloy by pouring the molten aluminum or molten aluminum alloy at 580° C. to 900° C. into the preheated tundish to fabricate an enveloped-cast plate with a predetermined thickness; and cutting off shrinkage cavities formed in a feeder section in an upper part of the enveloped-cast plate.
