FARMINGTON, CT (April 2013) – Porous metal has been widely used as a material of choice for advanced technology applications in a broad cross-section of industries. Robust, rugged, highly resistant to corrosion, shock and vibration, porous metal is ideal for providing highly dependable filtration or for controlling consistency in fluid flow under the most demanding conditions.

Mott’s sintered porous metal products can be used in many filtration and flow control applications for vehicles in the automotive, heavy equipment / machinery, off-road, and rail industry. Applications include; flow control and filtration for engine controls, emission controls and emission control systems, as well as for manufacturing and aftermarket test equipment. Porous metal has also been used in a variety of fuel cell technologies, as well as in stationary hydrogen generating units and stationary/standby power generation systems.

Fuel Filtration

Mott provides porous metal fuel filter assemblies used in diesel engines. These filters have replaced other types of filters as they are more robust and able to endure demanding conditions characteristic of diesel engines (such as strong vibrations). Mott porous metal filters are effective for coarse filtration (20-50 micron) down to sub-micron filtration (0.2 micron or less). They are also engineered to withstand thousands of pounds of pressure.

Fluid Controls

Mott porous metal flow restrictors are used in automotive leak tightness testing equipment. The test uses air or nitrogen and the result correlates to a liquid leak rate. The restrictors function as ‘calibration leak standards’; they are used to calibrate the component that measures the gas leak. The multi-pore construction of a Mott restrictor gives it an advantage over an orifice restrictor. The Mott restrictor is less susceptible to flow rate variation as a result of clogging by debris that may be in the test gas. Since a Mott restrictor contains thousands of three-dimensional pore pathways, gas can easily flow around an obstructed area. Once calibrated, a porous metal flow device will never deviate from its calibrated flow as long as the supply gas pressure and cleanliness are maintained.

Fuel Cells / Hydrogen Generation

Porous metal has been successfully used in a variety of alternative energy and green energy applications and is an outstanding material for use in PEM or SOFC fuel cells, flow batteries, electrolyzers, and other alternative energy devices. Rugged and robust, porous metal can be processed with smooth, scratch free surfaces that can be used as a membrane support, catalyst support, gaseous diffusion layer or as an electrode in cell stacks or cell assemblies

The benefits of Mott’s porous metal media are derived from its all-metal and sinter-bonded construction. The alloys offered possess practical corrosion resistance in automotive environments. (As an example, 316L stainless steel is compatible with biodiesel.) These products also provide practical heat tolerance as a result of resistance to oxidation and retention of strength at elevated temperatures. The metal powder compaction, furnace sintering, and diffusion-bonding create a structure with a valuable combination of strength and ductility. Porous metal is far superior to non-metallic products for high stress environments.

Established in 1959, Mott Corporation has long been dedicated to applying sintered porous metal to gas and liquid filtration and flow product concepts. Our products are used by customers in industries such as medical device, chemical, alternative energy, semiconductor, analytical instrumentation, aerospace, and refineries just to name a few.
