*Reduce machining time.

Advantages of gray iron

*Gray iron refers to a class of ferrous alloy normally characterized by a microstructure of flake graphite in a ferrous matrix. It is named after the gray color of the fracture it forms, and it is the most commonly used cast iron. Gray iron is, in essence, an iron-carbon-silicon alloy that contains 2.5 to 4% C, 1 to 3% Si, and other small alloy additions.

Benefits/properties of gray iron:

*Relatively low cost

*Excellent machinability and wear resistance

*High thermal conductivity

*Excellent damping capacity

*Low solidification shrinkage
(compared to non-graphite precipitating irons)

*Excellent castability

Advantages of ductile iron (nodular iron, SG Iron)

*Ductile iron is a cast iron in which the precipitated graphite present is in the form of tiny spheres or nodules because of additives introduced to the molten iron before casting. The resulting microstructure gives ductile iron higher strength, more elongation, and greater toughness than gray iron.

Benefits/properties of ductile iron:

*High strength-to-weight ratio

*Excellent surface detail and finish

*Excellent machinability and wear resistance

*Reduced weight compared to steel

*Excellent castability

Can replace some steel forgings, cast carbon steel, and fabrications

General capabilities

*Pouring gray and ductile iron castings from 150 to 5,000 pounds to ASTM specifications

*Air-set/no-bake, chemically bonded sand for precision castings

*Producing a range of iron castings, including complex, highly cored parts at close tolerances to basic parts requiring no cores

*Austempered ductile iron (ADI) specialized heat treatment process for superior strength

*Producing 1,000 tons of finished iron castings per month

*Production runs from 1 – 200 per month

*Gray iron Class 20-50 & Ductile 100-70-03, 80-55-06, 65-45-12 & 60-40-18

*Complete pattern layout and design with 2D & 3D capabilities

*On-site pattern storage

No-bake method

*High degree of repeatability

*Ability to hold tight tolerances

*Requires less machining

*Excellent casting soundness for pressure-sensitive application

Long-term savings

*Lower rejection rate

*Lower “through costs” on machining & assembly, eliminating re-machining and re-testing costs

*On-time deliveries
