Here is a quick fact for you that not all iron is magnetic. A lot of people wonder that is cast iron magnetic? Well, you must know that there are different types of iron and not all are magnetic. There is a physical change that can or not make them magnetic. And, that list includes cast iron. There is a lot of research going on cast iron as well and its properties that make it so amazing. 

You must know that iron is ferromagnetic which means it can easily attract magnets. But, this occurs at a certain temperature and every metal has its range and specific conditions. It can attract a magnet below its Curie point. Above the normal temperature like 770 degrees C, it is paramagnetic. It means that at this point it cannot attract magnets. 

People who ask is copper magnetic or is titanium magnetic must know that they are in their specific condition. Cast iron is one of the types of iron that have a weak tendency to attract magnets. You must know that cast iron is brittle and make it a poor choice when you want to make them into shapes. But, people use it for automotive parts because of its paramagnetic strength. 

Is Cast Iron Magnetic? Properties of Cast Iron:

Cast iron has properties that make it so different than steel. Let’s check them out:

  1. It can be ferromagnetic but it mostly shows paramagnetic strength that makes it so superior to automotive
  2. Famous for its tensile strength around the world for heavy machinery
  3. It is less viscous and has high fluidity 
  4. Highly brittle that’s why not a good option for making it into shapes 
  5. You cannot forge it into anything simpler 
  6. It also shows a great castability with high fluidity 
  7. Moreover, it has a good damping capacity 
  8. It shows quite a resistance to corrosion and rust making it a perfect choice in the automotive. 

Is Cast Iron Magnetic? Types of Cast Iron:

Well, you must know the different types of cast iron. The most common type is grey cast iron which is different than the rest due to its specific properties. Cast iron contains a lot of carbon when you compare it with steel. It could be more than 3 to 5% that absorbs into the iron making it an alloy. If you ever see cast iron, you can see that it has a structure of graphic withing on it. 

In the grey cast iron, the graphite form sharp edges and cracks. Due to its poor strength and no forging property, it is not a good option for many industrial uses. However, when it comes to the stiffness of cast iron, nothing can break its worth. The best part is that at its low melting point it becomes a molten fluid. You can create large and complex forms with it which makes the procedure inexpensive.

You can do this with any technology and it is easier to deal with than steel. Must know that the steel industry requires a lot of money and the best technology. So, cast iron is fairly simple. The graphite in the cast iron also gives it a vibration-damping property that makes it relatively hard. Its stiffness is the reason it is of good use in the industry. 

Is Ductile Cast Iron Magnetic:

We have discussed the properties of cast iron that how it is and can change in temperatures. Cast iron is great because it’s cheaper and lasts a lifeline than many other metals. You might have heard even that there are cast iron trays as well. People use them to make steaks on it. Yes, it does not affect your health at all as other metals can. 

You might be using cast iron at home if you like to make a juicy steak for dinner. There are quite simple applications for cast iron as well which makes it a good choice. But, you must know that it is not like other types of iron. The best part is that it will not affect your health at all. Now, you might know the answer is iron cast magnetic. Read above its properties to know more about its strength and paramagnetic property.
