Ductile iron VS Gray iron
Cast iron is a necessary good partner for machining.
Different cast irons are used on different machines. There is two famous cast iron: ductile iron and gray iron
Large machine needs high bearing capacity and non-deformation fixture.
Auto-Strong owns integrity, honesty and pragmatic treatment to all our customers.
We also manufacture high-quality products that customers can trust with a rigorous and responsible attitude.
Auto-Strong large chuck 21 inches or above (including) hydraulic power chuck uses "FCD600 Ductile Iron" material.
In ductile iron, graphite flakes are transformed into
tiny spheres through special processing methods.
These tiny spheres make ductile iron have better ductility and impact resistance.
Therefore, these graphite balls are called "Crack Terminators" because of their ability to prevent breaks.
AutoStrong’s philosophy and persistence is to provide the best quality for our customers.
AutoStrong products have global liability insurance every year,
which provides a layer of protection for your products with selected materials.
Large wedge type non through-hole power chuck (adapter excluded)
Chucking operations of very large components external or internal clamping.
Suitable for vertical lathe, due to the front protection of slide way.
Master jaw with manual radial setting function.
- Low Cost
- Good Shock Absorption
- Low Plasticity
- High Brittleness
- Low Impact Force
Gray iron and ductile iron can be explained by two biscuits.The both of mechanical properties are different, and the way of breaking is also different.
- High Hardness
- High Tensile Strength
- High Ductility
- Hard To Deform
- Impact Resistance
The tensile strength of ductile iron is 60K, and gray iron is only 31k.
The yield strength of ductile iron is 40K. Gray iron does not clearly show the yield strength and the toughness is almost zero, which is easy to crack and break.
