Product type
Grey cast iron is a type of cast iron that is characterized by its graphite microstructure, which gives it a grey appearance when fractured. This material is made from iron, carbon, and silicon, and is known for its excellent castability and machinability. Grey cast iron is commonly used in a variety of industrial applications due to its good wear resistance and ability to dampen vibrations.
| Material Composition | Iron, carbon (2.5% to 4%), silicon (1% to 3%) |
| Density | 6.5 to 7.8 g/cm³ |
| Tensile Strength | 150 to 400 MPa |
| Hardness | 170 to 250 HB |
| Casting Process | Sand casting, shell molding |
| Thermal Conductivity | 50 to 60 W/m·K |
When selecting grey cast iron, buyers should consider the specific grades required for their application, as different grades offer varying mechanical properties. It's important to specify the desired hardness, tensile strength, and any relevant certifications. Additionally, quantities and tolerances should be clearly defined to ensure that the material meets the intended use.
