Differences Between Ductile Iron Vs Cast Iron

This article will discuss what are ductile iron or cast iron; which is better? What are some of the differences between these materials? How do they differ? How is ductile iron used?


There are many different shapes of ductile iron but the main difference between ductile iron or cast iron in these is the strength. Cast Iron on the other hand is weaker than ductile iron, because ductile iron itself is much stronger than cast iron. Cast Iron when bent is very hard to make into any different shapes and therefore is primarily used in its unbroken state, as in casting for different shapes. Cast iron when bent is very much flexible and can be made into many different shapes, as in dentles.


The strength of ductile iron or cast iron comes from the properties of the metals when they are bent; ductile iron is much more ductile than cast iron when ductile cast iron has been bent into many different shapes. When both metals have been bent into the same shape it is known as compression or torsion spring. When the metals are bent into different shapes and then the ductile iron is hardened, it becomes harder to handle than the cast iron. The harder the metal is to handle the greater the toughness.


Cast Iron pipes are much stronger than ductile iron; the reason being that ductile iron is actually a soft metal whereas cast iron actually is not. When you take ductile iron and cast iron pipe and weld them together they create a really strong chemical reaction which results in much stronger pipe. These pipes are much better at dissipating heat than cast iron because they are not made out of pure iron. This gives these pipes a resistance to high temperatures of up to 350 degrees Celsius, which is more than can be said for cast iron. Cast iron pipes are also more resistant to corrosion than ductile iron and so are able to withstand chemical reaction that will corrode ductile iron.


There are many advantages and disadvantages of ductile iron or cast iron. One of the major disadvantages of ductile iron castings is that if you have to repair or replace your pipe it can be harder than you first thought. The process of welding them together can also be difficult. If you are unable to replace or repair your pipe then you may find that you will have to pay much higher than you would have if you had chosen cast aluminium for your pipe.


When it comes to differences between ductile iron or cast iron there are many factors at play. These include the quality of the end product, which one you choose should ultimately depend on your particular needs. One thing that you might want to consider when deciding which is best for you is the cost, because you will find that the price difference between ductile iron pipe and cast aluminium pail is not that big. Some of the other things to take into consideration are the warranty on the product and the material used to make it. You will also need to take into account other factors such as the size of the pipe you need to use. There are many more factors than these, but this should give you a good idea as to what you need to look for.
