蠕墨铸铁的物理与力学性能介于球墨铸铁与灰口铸铁之间。由于石墨结构是紧密的、端部呈圆形,减少了割裂基体的作用。故当成分一定时蠕墨铸铁的强度比片状石墨铸铁要高,另一方面又由于石墨互相连接,故蠕墨铸铁的强度与韧性又不及球墨铸铁,但其 Compacted graphite cast iron physical and mechanical properties between the ductile iron and gray cast iron between. Because the graphite structure is compact, the ends are rounded, reducing the effect of splitting the substrate. Therefore, when the composition of vermicular graphite iron cast iron strength than the flake graphite cast iron to be high, on the other hand because of the graphite connected to each other, so vermicular cast iron strength and toughness less ductile iron, but its
