Gray cast-iron machines readily because the flaky graphite particles in it cause the chip to break readily.
Malleable cast iron also machines easily, but the nodular shape of the free carbon is not so effective in breaking ;the chip.
Wrought iron, which carries many tiny threads of slag, machines easily until the harder slag dulls the tool.
