Gray Iron Casting
With its wide range of mechanical properties, Gray Iron Casting is suitable for
many engineering applications, especially where intricacy of design is required.
Gray Iron Casting is commonly used when ductility is not a factor.
Typical Applications for Gray Iron Casting:
Gray Iron Casting is particulary well suited for General Machinery, Stock Fittings,
Automotive Parts, Valve Bodies, Railroad Accessories
Advantages of Gray Iron Casting:
Gray Iron Casting provides advantages in the areas of Cost, Excellent Machining,
Dampening Capacity (ability to absorb vibrations). Good Wear Characteristics (self
lubricating), Compressive Strength
