Foundry Cast Iron: Gray Cast Iron
Gray cast iron is a popular material used in various industries due to its excellent properties. It is available in different grades such as GG20, GG25, and GG30. The weight of the cast iron ranges from 0.8 to 5000Kg, with dimensions varying from 30 to 3000mm. The wall thickness can be as thin as 6mm or as thick as 400mm.
One of the key advantages of gray cast iron is its rust-proof nature. It can be coated with paint or galvanized to enhance its resistance against corrosion. This makes it suitable for applications where exposure to moisture or harsh environments is expected.
