Hi Has anyone tried to shrink a tungsten ( carbide ) object This is a sintered metal under extreme pressure with a binder of silver or cobalt melted into the matrix after forming in a kiln. The binder concentration is about 15% I work in industry with tungsten as a cutting tool Question, the shrunken coin weighs what percentage of original? Regards Greg Jacob

Hi Greg,
The shrinking operation simply reshapes the object. The mass and volume are not changed.
In addition, brittle alloys or composites would likely be shattered during the process rather than being reformed into a different shape. Because of the high electrical resistivity of sintered tungsten carbide material, shrinking forces will also be relatively low. However, we have not actually tested this material in the Shrinker.
