* shrinkage expansion after solidification: Clow136 skrinks 2x10-4. For a thickness of 2mm, that is less than 1 micron, so probably irrelvant. For Field's metal, we don't know. | * shrinkage expansion after solidification: Clow136 skrinks 2x10-4. For a thickness of 2mm, that is less than 1 micron, so probably irrelvant.
