Porous Sintered Metal Powder
Porous Sintered Metal Powder can be different sold sintered alloy material powders, which are mainly used for 316L level or above. It can resist most chemical substances and also can be used to produce other levels of powder sintering materials, such as chromium-nickel-iron alloys, Hartz， and Monel. Meanwhile， it can be used in sintered bronze powder medium, which are porous sintered materials sintered in different temperatures. It can be made into sintered products with the shape of a disk or cylinder.
Powder sintering material is a depth-based filtration element. The characteristics of sintered porous material are high efficiency, adaptive construction, uncomplicated maintenance, and high mechanical and temperature durability, which lead to long service life. There are various porosity levels of Saifilter materials, which can be realized by changing the particle shape, size， and distribution of the metal powder used. Through the change in the manufacturing process, the flow, porosity, strength， and other exceptional physical properties can be accurately regulated.
sintering process in powder metallurgy
Two radically different manufacturing processes and two different kinds of powder are used to produce the porous sintered solid, namely “pressing sintering” and “unconsolidated powder sintering”
Pressing sintering
The powder is cold-pressed to form banks of required density. These so-called green bodies are sintered in a protective gas or vacuum furnace at the temperature corresponding to the material and can be manufactured without any external force or mold.
Unconsolidated powder sintering
Fill these powders to the mold and dispose of the vibrating compacting. Sintering is done in the mold and special furnace gases without additional pressure.
In addition to the above sintering process, material properties can be influenced again according to the process requirements, such as closing the holes purposefully in a place where no flow is needed through mechanical processing and different shape requirements are met through wire cutting or laser cutting.
In addition to standard plates, tubes, molded goods, etc., welding components of any size can be made from Saifilter material.
Heat stability can be up to 650℃（1020°F）
Accuracy class can be up to 0.2-80μm
30-45% porosity is calculated by volume: 30-45%
Density: 5-7.5gm/cc
