Gray iron and ductile iron are among the most common types of iron used in sand casting. Gray iron has good fluidity, making it suitable for casting intricate shapes. It is used for a variety of applications, including engine blocks, pipes, and heavy machinery parts. Ductile iron, on the other hand, offers enhanced strength and ductility compared to gray iron, making it perfect for parts that require better mechanical properties, such as gears and automotive suspensions. The versatility and durability of iron make it a top choice for many industries.
