Methodology

Cast Iron density and calculation basis

Evidence status: publishable.

Representative gray cast iron density; ductile iron and other grades differ.

grade: Dura-Bar gray cast iron

Source basis: Dura-Bar, Density technical brief, 02/2019. Technical brief: gray iron versus ductile iron density. https://www.dura-bar.com/getmedia/811341e6-6541-48f9-b719-1d1d666a2bc8/dura-bar-density-0219.pdf?ext=.pdf Applicability: adopted-context.

Ductile iron has a separate 0.255 lb/in³ value; temperature not stated.

For this direction, mass is calculated as volume multiplied by density after normalizing the units to cubic meters and kilograms. The resulting page multiplier is 27.254965 kg per gal (US).

Use a measured density for a specific batch, grade or supplier; the table value is a reference, not a product specification.
