[Overview] Iron castings can be made into many complex part. It is good in terms of cutting performance. In addition, the iron casting has good wear resistance and shock resistance. Its price is also very low.
Industrial iron castings' carbon content is usually 2% to 4%. Carbon in the iron castings mostly exist in the form of graphite, and sometimes also exist in the form of cementite. In addition to carbon, the casting contains 1% to 3% of the silicon, but also contains manganese, phosphorus, sulfur and other elements. And alloy iron casting actually contains nickel, chromium, molybdenum, aluminum, Copper, boron, vanadium and other elements.
In conclusion, the iron casting's mechanical properties is lower than the steel casting's which has the same material. But forging processing can ensure the continuity of metal fiber organization, so that we will note that in some degree, it will make the cast iron pieces' fiber and forgings maintain the same shape.
The iron casting's metal flow line is more complete, which ensures the parts have better mechanical properties and long service life. And the iron casting uses precise die forging, cold extrusion, warm extrusion and other processes for production, which is much better than other casting.
The iron casting itself has very good machinery and physical properties, and it also has a variety of different strength, hardness and toughness. Moreover, it may has one or many special performances at the same time..
