Read through this ScienceStruck article to know more about the properties of this variety of iron. Pig iron can be melted down to form cast iron, which is useful for a number of engineering purposes.

While the pig iron that forms its basis is being melted, scrap iron and steel are often thrown into the mix. Cast iron has become a synonym for durability — a cast iron stomach or alibi. cast iron: [noun] a commercial alloy of iron, carbon, and silicon that is cast in a mold and is hard, brittle, nonmalleable, and incapable of being hammer-welded but more easily fusible than steel. While cast iron withstands compression force very well, this brittle … Cast-iron skillets are made by pouring molten metal into a sand mold, which is broken apart when the pan cools, allowing the pan to emerge in one piece, handle included.

Other problems faced during the cast iron process include contamination of the iron, gas porosity (the forming of bubbles in the iron), and problems with the fluidity of the metal. It is made by reducing iron ore in a blast furnace. Read through this ScienceStruck article to know more about the properties of this variety of iron. Cast iron, an alloy of iron that contains 2 to 4 percent carbon, along with varying amounts of silicon and manganese and traces of impurities such as sulfur and phosphorus. As metals go, however, it is actually something of a Brunswick stew. Cast iron that has not cooled evenly produces a low-quality cast.

Cast iron's seemingly contradictory properties help make the ferrous metal more intriguing. The liquid iron is cast, or poured and hardened, into crude ingots called The casting process is an art that must be examined and experienced to be fully understood.
