What are Advantages of cast iron?
Cast iron is one of the most extensively used alloys of ferrous. It is made from pig iron by the process of casting and hence the name. Pig iron is placed in the furnace along with other alloying elements and melted until the molten mixture is obtained. The molten mixture is then poured in casts or molds of required dimension and left to solidify. The resultant solid obtained is the cast iron which finds its use in a myriad of industries. Advantages: 1. Good castability (low Tm, good fluidity) 2. Good machinability (graphite cast irons) 3. Antivibration properties 4. Low-stress concentration 5. Sensibility Types of cast iron The properties of iron casting can vary according to the alloying elements added. The cast iron’s properties can be manipulated by varying the alloying constituents. The main alloying elements added to the cast iron are carbon and silicon. Based on the amount of the alloying elements added, the cast iron can be classified into grey iron or white iron. Th
