Cast iron is a group of iron-carbon alloys with a carbon content greater than 2%. It is known for its excellent castability, wear resistance, and machinability. Cast iron is typically produced by melting iron and adding carbon and other alloying elements, which gives it unique properties suitable for various applications. The material is commonly used in the manufacturing of heavy machinery, engine blocks, pipes, and cookware due to its durability and ability to withstand high temperatures.
| Material Composition | Iron with 2-4% carbon and other alloying elements |
| Casting Process | Sand casting, shell molding, and die casting |
| Tensile Strength | Typically ranges from 200 to 600 MPa |
| Hardness | Usually between 150 to 300 HB |
| Melting Point | Approximately 1200 to 1300┬░C |
When selecting cast iron, consider the specific application and required properties such as tensile strength and hardness. It's important to specify the desired grade of cast iron, as different grades (such as gray iron, ductile iron, or white iron) have distinct characteristics. Additionally, buyers should clarify tolerances and any necessary certifications, especially for applications in regulated industries. Quantities should also be specified to ensure proper production and delivery timelines.
