Every product will be fully tested before it's packed for shipment.The advantages & disadvantages of gray cast iron  Gray iron is a versatile, low-cost alloy with a long history and many manufacturing applications. Gray iron's high carbon content gives it a dull, grey appearance with low reflectivity. Common uses for grey cast iron include pipes, cookware and automobile parts.  Advantages  Gray iron's high carbon content makes it easy to melt, weld, machine and cast using common metalworking processes. Gray iron contains graphite flakes that provide a high level of stability and minimise shrinking during the casting process. The metallurgy of grey iron also makes it resistant to corrosion. Gray iron's high conductivity makes it ideal for cookware.Disadvantages  Gray cast iron's extremely low tensile strength makes it a poor shock resistor relative to newer, less rigid iron alloy varieties. Blasting grey iron can weaken castings by causing residual stress. Gray iron may be too brittle for some applications, including instances when a casting must be especially thin or flexible.
