Sintered Metal Filters: A Complete FAQ Guide


A: Features of Sintered Metal Filter


1. What is a Sintered Metal Filter

     A short definition of sintered metal filter: It is a metal filter that uses metal powder particles of the same particle size

to be shaped by a stamping, high-temperature sintering proce Sintering is the process of metallurgy using powder-sized

bodies of different metals and alloys after stamping.

Metallurgy occurs by diffusion at temperatures below the melting point of high-temperature furnaces. The metals and alloys

commonly used today include aluminum, copper, nickel, bronze, stainless steel, and titanium.


There are different processes you can use to form the powder. They include grinding, automation, and chemical decomposition.


2. Why use Stainless Steel Metal to make Filter? 

      To Choose Stainless Steel Metal as the main materials, just because have many benefits for stainless steel

   1. Not easy to rust 

   2. The sintering temperature does not need to be too high

   3. Pores are easy to control during sintering

   4. Sintered molding is more durable and not easy to deform

   5. Easy to clean


3. How is a Sintered Metal Filter Made ? 

      For the manufacturing process of Sintered metal filter, main have 3-steps as follow:

      A:  First step is to get the power metal.

          The metal powder, You can obtain metal powders by grinding, automation, or chemical decomposition. You can combine one metal

powder with another metal to form an alloy during the fabrication process, or you can use only one powder. The advantage of sintering is that

it does not change the physical properties of the metal material. The process is so simple that the metal elements are not altered.

       B:  Stamping

       The second step is to pour the metal powder into a pre-prepared mold in which you can shape the filter. The filter assembly is formed at room

temperature and under stamping. The amount of pressure applied depends on the metal you are using, as different metals have different elasticity.

After a high-pressure impact, the metal powder is compacted in the mold to form a solid filter.  After the high-pressure impact procedure, you can

place the prepared metal filter in a high-temperature furnace. 

        C:  High-temperature sintering

        In the sintering process, the metal particles are fused to form a single unit without reaching the melting point. This monolith is as strong,

rigid, and porous a filter as the metal.

        You can control the porosity of the filter by the process according to the flow level of the air or liquid to be filtered. 


4. What is the Process of Sintering? 

    One important step is Sintering,  so what is the process of sintering and to be metal filters ?

     You can check as follow chart to understand clear. 

sintering melt filter process picture


5. What Are the Main Specifications of Sintered Metal Filter? 

     After the process of stamping and high temperature sintering, we can get the sintered metal filters, then in

order to know the quality of the sintered filters, normally, we will test some data of the filters, if the data reach

the requirements as the clients asked, then we can release to arrange to shipping out.  

1. Porosity
2. Compression test
3. Flow test (gas and liquid)
4. Salt spray test (anti-rust test)
5. Dimensional appearance measurement


If still like to know more about sintered filter working principle, please check our this blog check details.


B: Application of Sintered Metal Filter


6. Where is the Application of Sintered Metal Filters? 

      As our clients refer some main application of the sintered filter as follow :

     1.) Liquid Filtration   2. Fluidizing

     3. Sparging              4. Diffusion

     5. Flame Arrestor     6. Gas Filtration 

     7. Food and Beverage  


7. Can l Use Sintered Metal Filters with Multiple Types of Oils? 

      Yes, but need to customize special pore size as the oil , also the flow control requirement, so

       you can welcome to contact us to let us know your details.  


8. Can a Sintered Metal Filter Continue to Work Even when the Conditions are Freezing?

     Yes, for sintered metal finter, such as 316L sintered stainless steel filter can work under

-70 ℃~ +600℃ , so  for most of sintered filter can work under freezong. but need to ensure

Liquid and gas can flow under the freezing condition. 


9. What Kind of Chemicals Can filter by Sintered Metal Filters and Without Harming the Filter Body ? 

      We test most of chemicals that can be moved through this particular product without harming it, 

     such as phenol given that they are made using strong chemical-resistant materials. 

    1. ) Acid

    Strong acids: include sulfuric acid (H2SO4), nitric acid (HNO3), and hydrochloric acid (HCl).

    Weak acids in high concentrations, such as acetic acid

    B Lewis acid solutions with special chemical properties, such as zinc chloride

     2.)  Strong Bases: including sodium hydroxide (NaOH) and potassium hydroxide (KOH) 

       Alkali metals (such as sodium) in their metallic state Alkali and alkaline earth metal hydrides 

       High concentrations of weak bases such as ammonia

     3.)  Dehydrating agents, including high-concentration sulfuric acid, phosphorus pentoxide, calcium oxide,

       zinc chloride (non-solution), and alkali metal elements

     4.)  Strong oxidizing agents, including hydrogen peroxide, nitric acid, and concentrated sulfuric acid.

     5.)Electrophilic halogens such as fluorine, chlorine, bromine, and iodine (the ions of halides are not corrosive),

       and electrophilic salts such as sodium hypochlorite.

      6.) Organic halides or halides of organic acids, such as acetyl chloride and benzyl chloroformate anhydride 

      7.) Alkylating agents such as dimethyl sulfate 

      8.) Some organic compounds 


C: Order Information Sintered Metal Filter

10. Can l Customize sintered metal filter when Ordering from HENGKO?

    Yes, Absolutly Sure . 

    We can O.E.M  Sintered Metal Filters as your as follow specification requirements list :
