Sand Casting Materials
Grey Cast Iron
Austenitic cast iron
Spheroidal graphite iron
Grey Cast Iron
High resistance to abrasion with good dampening characteristics.
Grey cast iron is the most widely used iron-carbon alloy in casting. It offers high resistance to abrasion and excellent vibration dampening, making it ideal for heavy-duty applications. Thanks to its good pouring capability and easy machinability, it is cost-effective for complex shapes. Its unique graphite flake structure provides these benefits, though it also results in low ductility compared to other alloys.
Applications :
Heavy duty parts, machine bases, engine blocks
