5 Best Heat-Resistant Materials and their Uses

As we try to explore more, build better devices, and go to outer space, we need to keep up with the obstacles and find solutions to the most common problems. It is said that one of the biggest obstacles in the manufacturing, aerospace industry, and the military is the heat.

We are working with extremely high temperatures, and we need to work with materials that are not going to melt or get damaged during the production process and when they are implemented in real life.

If you have been wondering what are the substances that are used when working with high temperatures, you’ve come to the right place. In this article, we are going to talk about some of the best heat-resistant materials and their uses. Keep on reading to find out where they are implemented and what we can expect from them.

1. Tantalum carbide

The first material that we are going to talk about is the one that holds the record when it comes to being heat resistant. This substance can withstand temperatures that go up to four thousand degrees Celsius, and it is used most commonly for projects that revolve around outer space. Many shuttles and components that need to be sent to space are made out of this material, and it is also used in aviation.

It is said that this material is groundbreaking because it can easily pave the way for better technologies and getting over obstacles that we have encountered before. It is said that because of this material, we can enter a time where we can think about hypersonic vehicles and focus on developing them without worrying about how they are going to react to the extremely high temperatures.

2. Tungsten

Another material that is used because of its extremely high melting point is tungsten. This is said to be the metal with the highest melting point, and it is around the 1600 degrees Celsius mark. Another reason why this material is so commonly used is because of its tensile strength as well as the thermal expansion rate. It is hard and of high density and it is ideal for many applications.

It can be commonly found in the field of the military as well as aerospace, and it is used for rochets and turbines. It can also be found in cathode ray tubes and heater coils. This metal is the most preferred one when manufacturers need a material that will not expand when it is subjected to high temperature and it also has an extremely low point of vapor pressure.

3. Inconel 718

This material is also known as a superalloy and it is a combination of Nickel and Chromium. Its melting point is around 1400 degrees Celsius and it has been reported that up until 700 degrees Celsius the material will not be affected in any way. It is completely resistant to corrosion, which means that even if it is submerged in water and placed in any type of environment, it will not get damaged in any way. It can be subjected to extreme pressure as well, without forming dents or getting damaged.

One important thing that needs to be mentioned is that this material is brittle which means that it can be easily shaped using the right tools. Just like the other two materials that we mentioned previously, this material is used in aerospace, but it is also implemented in the military and manufacturing. It is used to create engine parts, die holders, and compression casings.

When working with materials like this, it is important to find the right manufacturer to help you out, and as suggested by ADL Insulflex, the equipment used to treat and fabricate these materials is crucial for the success of the final result.

4. Tantalum

The next material on the list is Tantalum, and this is not only a substance that can resist extremely high temperatures, but it is also resistant to corrosion. This material is not commonly used alone instead it is combined with other metals to create superalloys. When you combine metals together, you are able to get the best out of them all and get a much more practical substance that will have the best properties from all of the components.

This material along with the superalloys that are created with it is most commonly used in nuclear plants, but it can also be implemented for jet engines as well as chemical plants. It can be used to create electronic components and it is one of the best choices when you are looking for a material that will exhibit excellent oxidation properties. Its melting point is close to 3000 degrees Celsius.

5. Stainless Steel

The last material that we are going to talk about is something that we have all heard of. One thing that is worth mentioning is that not all types of this steel are the same, and the 316L type is the one that manufacturers turn to when they need to create components that are going to be heat resistant. Its melting point is close to the 1500 degrees Celsius mark, and it can be used in places that go up to 1000 degrees Celsius in heat.

This material is stable when it comes to corrosion and it will not get damaged when it comes in contact with acids or chlorine-based substances. It is extremely versatile, and it can be used in pretty much every field and industry. We most commonly find it in the field of medicine, but it is also used in the military, manufacturing, and even aerospace and the automotive industry. Many things are made with it including different types of equipment, nuts, bolts, and even heat exchangers.

These are some of the many materials, metals, and alloys that are extremely resistant to heat, oxidation, and corrosion. Before choosing the right substance for your needs, you need to consider other properties and not just the melting point. Keep in mind that the overall conditions that these materials are going to be subjected to will play a huge role when it comes to their durability and their uses. The best thing you can do is talk to a professional and an expert that can advise you on which metal is the best one for your specific needs.
