What Are The Advantages Of Ductile Iron Castings

1. Nodular cast iron has strong corrosion resistance: nodular cast iron has graphite element into the gap of iron element, so that corrosive objects can not corrode iron element.

2. Ductile iron castings can also effectively prevent the generation of cracks: through microscopic observation, the technicians of the cast iron manufacturer found that the cracks produced by iron stopped after the graphite balls were cracked. This is because the graphite balls have very high stability and the probability of cracking is very small.

3. Ductile iron also has very good impact resistance and ductility: This is because the graphite flakes in the ductile iron will become very fine carbon elements through a special treatment, and these fine carbon elements will enter into the gaps of the iron elements, which will greatly strengthen the physical properties of the ductile iron and make the ductile iron have very good impact resistance. Cast iron manufacturers all know that iron has very good ductility, while graphite has no ductility. When the two are combined, they will have their own advantages. In this way, ductile iron will have both ductility and impact resistance.
