Continuous Cast Iron Bars
201 Type 1 Ni Resist Dura-Bar
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
Typical Applications
  • Valve Guides
  • Insecticide Pumps
  • Flood Gates
  • Piston Ring Inserts
  • Sea Water Valves
  • Pump Bodies
