Superior Quality Ductile Iron Alloys
Ductile iron, also known as spheroidal graphite iron, is an alloy of iron, carbon, and silicon that offers outstanding crack resistance and high ductility. Produced in Quebec, our ductile iron is ideal for industrial parts that demand reliability, strength, and cost efficiency.
Common applications: heavy machinery parts, pump housings, transportation components, bearing housing, gear box, gears, etc
Advantages of Ductile Iron
- Advantages of Ductile Iron
- High deformation capacity
- High yield strength
- Superior ultimate resistance
Properties and Composition of Ductile Iron
The graphite appears in spherical form, giving ductile iron superior resistance to rupture and impact compared to gray iron. This type of iron as an easy machinability and excellent resistance to fatigue.
