The sintering process is the backbone of creating sintered metal fiber filtration media. This intricate procedure involves bonding metal powders under high temperatures, short of their melting point. During sintering, the metal powders are carefully arranged and then exposed to heat in a controlled environment.
This heat treatment causes the particles to bond at a molecular level, forming a solid yet porous structure. The process requires precise temperature control and timing to ensure the integrity and consistency of the final product. The outcome is a material that combines the strength and heat resistance of metal with the desirable porous properties essential for effective filtration.
A significant advantage of the sintering process is the ability to control pore size and distribution within the sintered metal fiber felt. This control is achieved by adjusting the size and mixture of the metal powders used, as well as the sintering conditions.
By fine-tuning these parameters, manufacturers can produce filters with specific porosity levels and pore size distributions, tailored to suit various filtration requirements.
This level of customization allows for the creation of filters that can efficiently separate particles of different sizes under a wide range of operating conditions. The result is a highly versatile filtration medium that can be optimized for specific applications, ranging from fine chemical processing to heavy-duty industrial use.
Sintered metal fiber’s exceptional heat and corrosion resistance makes it a standout choice for challenging environments. This resistance is a result of the sintering process, which enhances the metal’s ability to withstand high temperatures and corrosive elements.
Such durability ensures that sintered metal fiber filtration systems can operate effectively in industries where exposure to extreme conditions is a regular occurrence. By maintaining their integrity in harsh environments, these filters offer reliability and longevity, reducing the need for frequent replacements and maintenance.
The mechanical strength of sintered metal fiber is unparalleled, thanks to the unique bonding process during sintering. This process creates strong fiber bonding, resulting in a filtration medium that can withstand high pressure, thermal shock, and frequent backflushing. This robustness is crucial in industrial settings where filters are subjected to rigorous use. The superior strength of sintered metal fiber filters not only ensures efficient filtration under demanding conditions but also contributes to the long-term durability and reliability of the filtration system.
Sintered metal fiber felt excels in filtration efficiency, meeting the stringent standards of HEPA and ULPA filters. This capability allows it to remove particles as small as 0.1 microns, making it suitable for applications requiring ultra-high purity levels. The high porosity and even distribution of fiber diameters contribute to its remarkable filtration performance, ensuring that both air and liquid contaminants are effectively captured. This level of efficiency is essential in industries like pharmaceuticals, biotech, and electronics, where even the smallest particles can have significant impacts.
Each of these features – heat and corrosion resistance, mechanical strength, and filtration efficiency – highlights why sintered metal fiber is a superior choice in advanced filtration applications.
When comparing sintered metal fiber felt with woven wire cloth, key differences emerge in their construction and performance. Sintered metal fiber felt is known for its high porosity and complex three-dimensional structure, which results in superior filtration efficiency. This structure enables it to trap finer particles more effectively than woven wire cloth.
Additionally, the sintering process imparts exceptional strength and durability to the fiber felt, making it resistant to high pressure and thermal shock.

Sintered metal fiber felt is a non-woven filter medium made by selectively laying and compressing fine metal fibers together and then bonding through the sintering process. High-temperature sintering ensures a uniform filter element that performs far better than legacy materials like glass fiber.
In addition to outperforming fiberglass, sintered metal fibers are very strong, corrosion-resistant, and able to withstand high temperatures and stress in some of the most challenging environments. The material is versatile and can be welded and folded into different shapes. It’s usually layered with standard wire mesh to create the desired performance in a filter element.
While there are many uses for sintered metal fiber, filtration is where this material shines. Its high porosity increases permeability up to 20 times compared to other media types. You can add the fiber felt as a single layer on a sintered filter element or sintered mesh. Alternatively, you can bond multiple layers through sintering to create a complete filter media.
It’s ideal for filtering gas and liquids, so it’s the perfect filter medium for the clients we serve here at FCP. Our metal fiber media has absolute filter ratings as low as 3 microns and will not shed or break like traditional fiberglass media. That’s why our all-metal filters are used in military jets and helicopters, commercial aerospace, and the marine industry.
Choosing sintered metal fiber felt as your filter medium is a wise choice. There are many advantages to using this type of media, including:
The fluid or gas passes through the filter, and the sintered metal fiber blocks and retains contaminants and prevents them from entering the system downstream. The particles cake on the surface of the media and continue collecting the pollutants. The more particles that build up on the surface of the filter, the more pressure drop increases until the filter reaches terminal pressure drop.
