Dura-Bar Products


Dura-Bar is stocked in several grades of ductile iron and gray iron, as well as additional non-stock grades which can be ordered in volume quantities from our distributors. The type and distribution of graphite influences most of the properties and results in the free machining characteristics, excellent noise and vibration damping, thermal conductivity and wear resistance.


Ductile Irons

Dura-Bar 65-45-12 and 80-55-06 ductile irons conform to ASTM A536, and are often used as an alternative to plain carbon steel, having similar strengths with excellent free machining properties.
