Cast Iron vs. Ductile Iron Housing Material

Apr 03, 2018  Ductile iron is typically twice as strong as many grey cast irons, and nearly as strong as steel. While ductile iron shares many of the advantages of cast iron, the ductile iron is more difficult to cast, and has a different shrink rate than cast iron. This difference means different patterns are required.

Ductile iron - Wikipedia

Ductile iron, also known as ductile cast iron, nodular cast iron, spheroidal graphite iron, spheroidal graphite cast iron and SG iron, is a type of graphite-rich cast iron discovered in 1943 by Keith Millis. While most varieties of cast iron are weak in tension and brittle, ductile iron has much more impact and fatigue resistance, due to its nodular graphite inclusions.
