Product type
Malleable cast iron is a type of cast iron that has been heat-treated to improve its ductility and toughness. It is produced by casting iron in a mold and then subjecting it to a heat treatment process that transforms the carbon content into a more flexible form. This material is known for its excellent machinability and resistance to wear, making it suitable for various industrial applications.
| Material Composition | Iron with carbon content typically between 2% to 4% |
| Heat Treatment | Typically annealed to improve ductility |
| Tensile Strength | Ranges from 370 to 700 MPa |
| Elongation | Typically between 2% to 10% |
| Standard Sizes | Available in various shapes including bars, plates, and fittings |
When choosing malleable cast iron, consider the specific mechanical properties required for your application, such as tensile strength and elongation. Additionally, specify the desired heat treatment process to ensure optimal ductility. Certifications may be relevant depending on the application, so inquire about compliance with industry standards. Be clear about the quantities needed to facilitate accurate quotes from suppliers.

Malleable cast iron is heat-treated for ductility, while ductile iron has a different microstructure that provides inherent toughness.
Yes, but it requires specific techniques and preheating to avoid cracking.
It is commonly used in automotive parts, construction fittings, and heavy machinery.
Malleable cast iron has limited corrosion resistance; coatings or treatments may be needed for harsh environments.
Sizes vary widely, including bars, fittings, and custom shapes depending on the manufacturer.
It should be stored in a dry environment to prevent rust and degradation.
