High-temperature alloys: what features do they have?

Many of the most important industries, such as military, aerospace, medical, high-precision electronics, and other leading sectors of the economy constantly need high-temperature alloys.

A key feature

This type of alloy has one key feature. It can maintain efficiency at temperatures greater than or equal to 500 °C. High-temperature alloys, which usually consist of one metal and another element, are known for their incredible durability and flawless performance under extremely harsh environmental conditions. High-temperature alloys can be used in any type of operation that requires materials capable of high durability and strength.

Excellent performance at high temperature

These alloys manage to perform very well at high temperature. It is necessary to be able to demonstrate their quality even at 1000 degrees, not just 500. For example, titanium alloys, do not exhibit adequate reaction at temperatures above 450 degrees. This limitation makes them unsuitable for use in jet and rocket thrusters. Other metals manage to offer better results in high-temperature alloys. Iron, nickel (an1), and cobalt are the base metals for alloys best suited for very high temperatures. In addition to these metals, alloys contain other elements, such as aluminum, zirconium, manganese or carbon. Additional metals that are very effective at high temperatures are rhenium and niobium.

The importance of using these alloys

The importance of using the most appropriate high-temperature alloys is critical, especially when using them for airplanes. If the use of the material in the application is directly related to the safety and well-being of people, the alloys must have performance that meets higher standards. High-temperature alloys must be produced using the best available materials and the latest techniques, without exception. The production of high-temperature alloys is extremely complicated and requires the use of advanced technologies. Finally, the production of high-temperature alloys is very costly, this is because both materials and machining for production are expensive
