^^ Just to correct an error so people don't get wrong info, Cast Iron has a CTE (Coefficient of thermal expansion) of 5.8 10e-6 in/in deg F, Aluminum 6061 or 7075 has a CTE of ~13.0 10e-6 in/in deg F, (not picking on you DE) the cast iron actually expands less than the billet aluminum by about half as much.
