Product Description
Grey iron, or grey cast iron, is a material type of cast iron with graphitic microstructure. We call this kind of material grey iron because of the gray color of the fracture. For the graphite lubricating the cut and breaking up the chips, grey iron is a common cast alloy due to its relatively low cost and good machinability. Besides, because the graphite flakes self lubricate, it also has good galling and wear resistance.
Grey iron also has less solidification shrinkage than other cast irons because of the graphite microstructure. Whe casting, the silicon element can promote good corrosion resistance and increase fluidity when casting. Gray iron is generally considered easy to weld. Compared to other iron castings, gray iron has a low tensile strength and ductility; that is why the impact and shock resistance of this kind of material is almost non-existent.

In our foundry, we can make grey iron castings in below two types:
Lost Foam Casting: The only investment casting process for cast iron components, which has lots of advantages to produce small gray iron invesmtent castings, such as saved mould cost, shorten production cycle and improve production efficiency. With lost foam casting process, we can help our customers to obtain high accuracy products with excellent surface finish, and less machining operations will be done.
Resin Sand Casting: Main sand casting process for small and medium castings. Compare with other sand casting processes, resin sand casting is relatively precise casting method close to investment casting. As good rigidity of resin sand and high strength of sand mould when early casting,then we could effectively eliminate the shrinkage cavity, shrinkage defects of gray iron castings.
