ABSTRACT:
An aluminum sheet having a prescribed thickness is obtained by compacting aluminum powder into a green sheet of packed aluminum powder, sintering the green sheet at temperatures of 300.degree. C to 600.degree. C and subsequently rolling and annealing the sintered sheet of aluminum powder at least once. A high-density sintered aluminum laminate is produced by piling a plurality of green sheets of packed aluminum powder one on top of another, sintering the pile of green sheets and then rolling and heating the sintered pile of sheets at least once.
