Sintered Porous Metal Discs. similar to a metallic sponge
Porous Sintered Metal Filters consist of highly uniform, interconnected networks of pores with tortuous paths that trap solid particles in gas or liquid flow streams. Excellent depth filters with superior mechanical strength. Stainless Steel Type 316L withstands temperatures up to 750°F (399°C) in oxidizing and 900°F (482°C) in reducing environments. These steam autoclavable filters can be cleaned by other methods, such as ultrasonic baths or reverse flow flushing. If your application requires even greater resistance to corrosion, temperature, wear, and vibration, other nickel-based alloys are available.
The material used to produce these filters is 316L stainless steel. They are made by uniaxial compaction of powder in a rigid tool with the negative shape of the part, and then sintered. The pore size is adjusted by changing the compaction pressure and/or the particle size of the powder.
Powder metallurgy technology is able to create other shapes, such as blind cylinders and other special geometries. In these cases it is necessary to build a specific tool according to the required design.
