Cast iron is a common material that has many uses. The material is more common than people believe it is.

Cast iron is made by heating and melting the iron.

What exactly is cast iron?

Cast iron is considered to be one of the most important materials that is used in the manufacturing of parts of different machinery, tools and it’s the most common material that is used in industries.

In this post, we’ll find out will a magnet stick to cast iron?

Will A Magnet Stick To Cast Iron?

Absolutely, a magnet will stick to cast iron; however, the force depends based on the quality of material.

Also, having the right magnet is key. Instead of buying a standard magnet like you would find on display at the “local home improvement store”, consider something like an extra-strong rare earth magnet or neodymium magnet instead. These are extremely powerful magnets that will easily magnetize most cast iron products.

They are also called “super magnets” for their ability to pick up and hold large loads.

·         Purity

Cast iron purity has an effect on the amount of magnetism it can create.

A lot of people think that cast iron is one type of metal that is either pure or impure.

However, this is not the case. Cast iron purity is more like a scale or a spectrum. A pure metal is one that is very high on the scale of purity.

The more impure it is, the lower it will be on the scale. The more impure a metal is, the more likely it will be to reject a magnet.

Most of the iron in the world is not pure. It is a mixture of different elements, most of which are not magnetic. However, you can have a pure form of iron that is so pure and easily attract magnets.

·         The Magnet

While there are different types of magnets, the most common magnets are synthetic magnets.

A synthetic magnet is a magnet that can retain its magnetic properties in the absence of a magnetic field. There are two types of permanent magnets: artificial and natural.

Natural permanent magnets are made of materials such as iron and cobalt. Artificial magnets, also called man-made magnets, are composed of materials such as alnico and ferrite.

So it depends on the type of magnet you’re using with the cast iron.  For your information, neodymium is the most powerful magnet on earth.

·         Size

Changing the size of a magnet will make a huge difference to its effects. Smaller magnets such as ferrite magnets (which are the strongest magnets around) do not have a lot of pulling power when compared to their larger counterparts such as neodymium magnets.

And will impact the attraction towards the cast iron.

Wrapping It Up

So yes, indeed magnet does stick to a cast iron.

Cast iron is one of the oldest materials in the world.

It has many use cases and its applications are diverse. As time has passed, its popularity has helped it to be improved upon.

There are many modern cast iron products available in the market.
