Ductile iron and gray iron composite brake drum
Invention patent number: 202110843768.5
![Ductile iron and gray iron composite brake drum Ductile iron and gray iron composite brake drum](/npublic/img/s.png)
1.The outer layer of iron-iron composite brake drum is made of high-strength ductile iron or high-strength creeping graphite cast iron, and the inner layer is made of wear-resistant gray cast iron; and the two are combined by metallurgy;
2.in the high temperature environment, the strength and stiffness of the attenuation is smaller
3.bimetallic iron iron composite brake drum than steel composite brake drum stiffness increased by about 50%, the service life can be increased by more than double.
4.more suitable for engineering vehicles that brake for a long time under harsh road conditions.
