What is the high temperature resistance of nickel foam?

Nickel foam is a porous metallic material with very high specific surface area and porosity, and its unique physical properties make it have a wide range of applications in many fields. The high-temperature resistance of nickel foam is the focus of many researchers.

High-temperature resistance of nickel foam
The high-temperature resistance of nickel foam mainly depends on its material and manufacturing process. Usually, the material of nickel foam is mainly pure nickel, as well as containing a certain proportion of aluminum, chromium, and other alloying elements. These materials have good thermal stability and corrosion resistance under high-temperature conditions, which enables nickel foam to maintain stable performance in high-temperature environments. Experiments show that at high temperatures of hundreds of degrees Celsius, the porosity of nickel foam hardly changes, and the surface morphology is unaffected.

Melting point of nickel foam
The melting point of nickel foam is one of the important indicators of its high-temperature resistance. According to the density and composition of nickel foam, its melting point is generally around 1350~1400℃. However, the actual melting point of nickel foam may vary due to different preparation processes and composition conditions. Therefore, in specific applications, the high-temperature resistance of nickel foam needs to be evaluated according to the actual situation.

High-temperature applications of nickel foam
The high-temperature stability of nickel foam makes it widely used in many fields. For example, in petrochemical and iron and steel metallurgy industries, nickel foam can be used as a filter for high-temperature gases and liquids to effectively remove impurities. In addition, nickel foam can also be used as a heat exchanger material for heating and cooling fluids, maintaining excellent heat transfer performance at high temperatures. At the same time, it can also be used as a carrier for catalysts to improve the reaction speed and catalytic effect.

Nickel foam has received widespread attention for its excellent high-temperature stability performance and wide range of application prospects. With the continuous progress of science and technology and the rapid development of industry, it is believed that the application of nickel foam in the field of high temperatures will be more extensive and in-depth.
