Sintered Metal Fiber

Diffusion Bonded / SinterPore™ Sintered Metal Fiber

The SMF series of filtration products provides the ability to achieve high filtration efficiencies from a combination of depth and tortuosity, while at the same time providing exceptional dirt holding capacity and flow characteristics.

Filter efficiency is achieved by the precise selection of fiber diameters and basis weight. The medium’s matrix is constructed to control the pore diameter throughout its thickness. This allows us to achieve a graded pore structure that captures the desired larger particles on the outer layers while resulting in a higher dirt holding capacity and subsequent longer on-stream life. The media can also be configured as a surface filter to trap particles on the outer layer if backflush or backpulse regeneration applications are desired.

Diffusion Bonded / SinterPore™ Sintered Metal Fiber products from Porous Metal Filters are used in many industries including Bulk and Powder Handling, Chromatography, Filtration Industry, Gasification, and Plant Oil Extraction.

Coil Sintering is a process that utilizes time, temperature, and atmosphere to secure or stick intersections of the wire mesh. The mesh can be calandered prior to heat treating to aid in bonding. The process produces a stable, secure mesh that is ideal for deep drawing and or reducing the risk of loose wire’s loose. This product is only available in single layer options.

SinterPore™ Sintered Metal Mesh provides many additional benefits when compared to traditional wire cloth.

Diffusion bonded wire cloth can be fabricated in single or multiple layers. Multiple layer assemblies provide enhanced mechanical properties for filters and harsh environment applications.
Sintered wire mesh is stable, making it ideal for mesh with a high percentage of open area or that requires a secure pore size.
SinterPore™ sintered mesh is easy to fabricate and produces a stable, strong product. It can be constructed as a depth filter media, providing excellent filtration properties. It is an excellent material to use for products that require controlled permeability.
Sintered wire mesh can be cleaned and re-used for many applications.
Diffusion bonding locks and secures all wire in the mesh, eliminating loose wires and increasing the stability of the cloth. It can be used for small parts and special shapes without losing shape or loose wires. Traditional wire cloth can become loose and ineffective over time.

Definition of Sintered or Diffusion Bonded Wire Mesh:

Stainless Steel Sintered Wire Mesh is a filtering cloth made by pressing multi-layer woven wire cloth, then sintered together in a vacuum furnace. This kind of filtering cloth is much better than common metal woven wire mesh with good strength, hardness and good positioning of opening. Its comprehensive property is superior to sintered metal powder and porcelain. The major characteristics are: excellent strength, no inner support is required for making filter elements, no material, easily repeated cleaning, long lifespan and good anti-corrosion.

What Are Sintered Mesh Laminates?

Fine woven wire filter mesh provides micron-rated pore size but it is too thin and can be damaged. The best solution is to laminate the fine mesh to a coarser mesh supportive layer to provide increased strength and thickness. The common sintered wire mesh laminates are 5-layer or 6-layer, which is extensively used in filtration.

Diffusion Bonded Filter Elements

DWT produces a wide range of filter elements utilizing sintered wire cloth. Sintered Wire Mesh elements have many advantages over standard filter elements.

Sintered Metal Filter Elements Advantages

Many elements can be cleaned and used multiple times.
Sintered Wire Cloth elements are much stronger than non-sintered elements.
Sintered elements have a stable pore geometry that is ideally suited for back flush filtration systems.
Available in a wide range of alloys. Most common is 316Lss and 304Lss.
Sintered Mesh Elements are available in a wire range of micron ratings (5 to micron) and can be custom designed to meet or exceed your filtration and performance requirements.
Sintered Metal Filters are commonly used in Hot Gas Filtration, Polymer Filtration and Oil & Gas Filtration.

Sintered Metal Filter Wire Cloth Alloys

304 Stainless Steel Sintered Wire Cloth

Most common stainless alloy used in wire weaving. Excellent corrosion properties and can withstand temperatures of Degrees F.

304L Stainless Steel Sintered Wire Cloth

Similar properties as 304ss but lower carbon content to permit better welding.

316SS Stainless Steel Sintered Wire Cloth

Similar properties to 304ss but is stabilized by the addition of Molybdenum for increased resistance to chemical corrosion.

316L Stainless Steel Sintered Wire Cloth

Similar properties as 316ss but lower carbon content to permit better welding.

904L Stainless Steel Sintered Wire Cloth

Hight resistance to corrosion and rust for sea water applications.

Nickel 200 Sintered Wire Cloth

Used in applications where high corrosion properties are required. Some applications could include several chemicals, caustics, and certain organic acids.

Monel 400 Sintered Wire Cloth

One of the most widely used alloys for high corrosion resistance. Used in many food and chemical processes. Monel is a registered trade mark for International Nickel Co INCO.
