Abstract
A process is disclosed for producing a sheet of tungsten heavy alloy which involves uniformly blending elemental metal powder components of the alloy by forming a slurry of the powder components in a liquid medium, introducing the slurry onto a filter medium and applying vacuum to the bottom of the slurry to form a planar cake of the powder components. The cake is then dried and sintered to a density equal to or greater than about 90% of the theoretical density of the alloy to form the sheet.
