*Technically, machinist's vises are almost always made of ductile iron, not cast iron. And yes, before some wag says "well they're cast in a mold, so it's cast iron," the phrase cast iron usually implies grey or white cast irons, which are brittle due to significant graphite content existing in the iron in flakes. Ductile iron's graphite is in a nodular shape which inhibits cracking. It's an important distinction in vises, because high quality vises are made from nodular or spheroidal (ductile) iron, and cheaply made economy vises (often imported) are made of grey cast iron
