Filters and foams

Standard Particle Size Distribution
10 50 μm

Metal powder technology is not limited to creating solid parts and coatings. It can also be used to create porous filters and foams that have unique properties and applications. 

To create metal filters and foams, metal powder is mixed with a binder to create a paste or slurry. The mixture is then formed into the desired shape using mold or 3D printing technology. The molded part is then heated to burn off the binder and sinter the metal particles together, creating a solid, porous structure. 


Metal filters and foams are versatile materials with a wide range of applications in industries as diverse as aerospace, automotive, medical, and industrial manufacturing. They are used for various purposes including filtration, catalysis and heat exchange. 

In filtration, metal filters and foams serve as an effective medium for separating contaminants from liquids and gases. They are used in various industries, including water treatment, oil and gas, and chemical processing, to filter contaminants and ensure the quality of the final product. 

Metal foams also have important applications in catalysis. They can act as catalyst supports in chemical reactions, allowing efficient and selective conversion of substances. This property makes them ideal for use in the chemical industry, where they can help increase the efficiency of chemical reactions and reduce production costs. 

In addition, metal foams can be used as heat exchangers, facilitating efficient heat transfer in high-temperature environments. They can regulate temperature changes in various industrial processes, making them essential in the aerospace and automotive industries, among others. 


High porosity

Metal filters and foams can have a high degree of porosity, allowing fluids and gases to flow through the material. This makes them useful in applications such as filtration and catalysis.

Strength and durability

Metal filters and foams are strong and durable, making them suitable for use in high-temperature and high-pressure environments.


Metal filters and foams can be manufactured in a wide range of shapes, sizes, and pore sizes, making them highly customizable for specific applications.
