Whether you want to import or learn more about sintered metal fiber felt, all information you are looking for is right here.
Keep reading if you want to be an expert in sintered metal fiber felt.
What is Sintered Metal Fiber Felt?
It is made of extremely fine stainless steel metal fiber (accurate to micron in diameter) which is made by non-woven layering and superimposed by high temperature sintering.
Sintered metal fiber felt is best suited for use in applications that operate under very high pressure, high temperature, and corrosive environments.
The stainless steel sintered felt is formed by different orifice gradients, which can be controlled to obtain high filtering precision and greater amount of contamination
The fleece of the metal fiber can comprise different layers of fiber.
They can be compressed together to a suitable thickness then sintered to fuse the respective single fibers..
What is the function of Sintered Metal Fiber Felt?
A sintered metal fiber felt is a porous material that offers superior filtration capabilities over other types of filtration media.
It has excellent filtration properties, which makes it a good choice for constructing a filtration element.
Consequently, you can add the material as a single layer on a sintered filter element or sintered mesh.
You can also sinter together multiple layers of the materials to construct a complete filter media.

How is Sintered Metal Fiber Felt Manufactured?
1. Heat the sintered metal fiber felt in a vacuum sintering furnace to between 300 ℃ and 600 ℃. Keep these temperatures for 30 to 120 minutes.
2. Carry out low temperature sintering. You will obtain a low temperature sintered metal fiber felt after natural cooling.
3. The low-temperature sintered felt is compressed by a hydraulic press to achieve a porosity of 60-90%.
4. The compressed sintered metal fiber felt is returned to the vacuum furnace and heated to 900C to 1000 °C. Keep the temperature for 1 to 30 minutes.
5. Carry out high temperature sintering. Let it cool naturally to obtain high quality sintered metal fiber felt.
