Porous Metal And Sintered Porous Filter Elements

Porous metal is made from powder, and then be compressed and fully sintered and then pruducted into the rigid structure. The media grades can be down to 0.1 Micron.

The porous metal filter element is made of porous metal powder through molding, isostatic pressing, etc., and then put into a high-temperature vacuum furnace for firing, taken out, cooled and annealed, and then customized and processed into filter products required by customers.

Due to the existence of a large number of holes in the metal material, the specific gravity of the material is significantly reduced. The specific gravity of the porous mold steel is only 5.0g/cm after testing, which is 34.2% lower than that of the non-porous material (7.6g/cm). .

In view of the good energy absorption characteristics of porous metal materials, it can be used to manufacture energy absorbers, shock absorbers, etc. for mechanical engineering and vehicle engineering. When they are subjected to a sudden impact, it is not easy to cause a vicious accident of car crash.

Some porous metal materials are obtained through the co-product solidification of metal and gas, so a large amount of gas is stored inside the material. As long as these pores are closed, when the material receives the energy of the vibration source, due to the large internal friction inside the material , and dissipate the transferred energy.

Porous metal materials also have good sound absorption capacity, so they are widely used as isolation materials for noise sources, such as porous aluminum alloys and magnesium alloys used in partition walls in submarines, which can well prevent sonar tracking. It is used for ceilings in places with noisy traffic, which can greatly reduce noise. In the future, the material can also be used in vehicles such as cars to reduce engine noise.

Porous metal materials have a large specific surface area, so they are used in electrochemistry to manufacture electrochemical electrodes, which can greatly improve the energy release during electrochemical reactions, such as foamed nickel electrode batteries. Due to the large specific surface area of porous metal materials, high heat exchange and heat dissipation capacity, good resistance to rapid cooling and rapid heating, and good sound absorption capacity, it is an ideal material for automobile exhaust processors.
