Porous Metal Meaning

What is Porous Metal

In Short, Porous metals are materials that have a three-dimensional interconnected network of pores, or voids, in their microstructure that allow fluids or gases to flow through the material. These pores range in size from nanometers to millimeters and are usually formed by processes such as sintering, foaming or electroplating. Porous metals have unique properties that make them useful in a variety of applications, including filtration, catalysis, energy storage, and biomedical engineering.

The porosity of these metals can be controlled and tailored to meet specific requirements, such as pore size, pore volume, and surface area. This tunability allows tailoring porous metals to meet the needs of different applications. Furthermore, the interconnected pore structure of porous metals allows high permeability and low pressure drop, which facilitates fluid flow and mass transfer processes.

Nowadays, Porous metals are usually made from common engineering metals such as aluminum, titanium, nickel and copper, but can also be made from less common materials such as magnesium or zinc. The properties of porous metals depend on the type of metal used, the manufacturing process, and the size and distribution of pores. Porous metals can be made in various forms such as sheets, tubes, foams and powders, making them versatile materials for a variety of applications.
