Material ChoicesConsider the following material options:
Malleable Iron: Small castings with thin wall sections (less than 3mm). Preferably high volume applications with good surface quality. Alloys for welding available. Dynamic loading at all temperatures possible. Best iron grade for machining. Magnetic. Conductive. Ideal steel substitute for welding applications or jobs requiring high ductility.
Gray Iron: Any casting size. Static applications with most economical solutions utilize this material. Machinable material for static cases.
Ductile Iron: Any casting size with wall thicknesses greater than 6mm or ¼ inch. Castings are machinable and useful for dynamically loaded applications.
