Product type
SG Iron Casting, also known as ductile iron casting, is a type of cast iron that has enhanced ductility and strength due to the presence of spherical graphite. This material is produced by adding small amounts of magnesium to the molten iron, which alters the structure of the graphite, resulting in improved mechanical properties. SG Iron is commonly used in various industrial applications due to its excellent wear resistance and ability to withstand high stress.
| Material Composition | Iron with added magnesium |
| Typical Tensile Strength | 400 to 800 MPa |
| Typical Yield Strength | 250 to 600 MPa |
| Elongation at Break | 5% to 20% |
| Casting Process | Sand casting, investment casting |
| Standard Sizes | Varies by application, custom sizes available |
When selecting SG Iron Castings, buyers should consider the specific mechanical properties required for their application, such as tensile and yield strength. It is also important to specify the desired elongation and any relevant certifications, such as ISO or ASTM standards. Quantities should be clearly stated, as well as any particular dimensions or customizations needed for the project.
