Continuous Cast Iron Bars
G1A Dura-Bar / Gray Iron
Description

Alro is a stocking distributor for Wells Manufacturing, the producers of the premier cast iron bars under the trade name of Dura-Bar. Cast irons are usually alloys that contain more than 2% carbon and from 1% to 3% silicon. Cast iron is offered in gray and ductile types. The primary difference in these types is the shape and distribution in their microstructure.

Dura-Bar offers a zero defect guarantee plus the inherent benefits of cast iron such as:

 
  • Improved Machinability
  • Lower Tool Cost
  • Decreased Downtime For Tooling Changes
  • Reduced Scrap By Using Defect-Free Material
