The differential housing is an important part of the differential, which plays the role of supporting, protecting and securing other components.
Ductile iron, as one of the most commonly used automotive parts materials, has many advantages such as high strength, high toughness, high wear resistance and good fatigue resistance.
Why do iron foundries use ductile iron to produce differential housings?
The differential housing needs to have high strength and toughness, and ductile iron is the material that can meet this requirement.
Compared with steel, ductile iron has a higher damping capacity, which can effectively prevent the noise and vibration generated by the vehicle during the driving process.
In addition, the differential housing made of ductile iron is not only compact in structure, accurate in size, easy to process, but also light in weight and economical and practical.
