Six Common Classification Of Cast Iron Accessories Introduced
- Jan 04, 2018 -

1, white cast iron. Carbon and silicon content is lower, carbon is mainly in the form of cementite, the fracture is silvery white. Shrinkage when solidified, easy to produce shrinkage, cracks. High hardness, brittleness, can not withstand the impact load. Used as a malleable cast iron parts and wear-resistant parts.

2, malleable iron. Obtained from the white cast iron annealed, graphite was flocculent group distribution, referred to as tough iron. Its uniform organizational performance, abrasion resistance, good ductility and toughness. For the manufacture of complex shapes, can withstand strong dynamic load parts.

3, compacted graphite cast iron The gray cast iron hot metal obtained after the vermicular treatment, precipitated graphite was worm-like. Mechanical properties and ductile iron similar casting performance between the gray cast iron and ductile iron. Used to make car parts.
