Powder sintered metallic porous material

Powder sintered porous metal material is made of metal or alloy powder as raw material by forming and sintering at high temperatures with a rigid structure.

It is characterized by a large number of connected or semi-connected pores inside, and the pore structure is composed of regular and irregular powder particles. The size, distribution, and porosity of pores depend on the powder particle size composition and preparation process.

Common sintered metal powder porous materials are bronze, stainless steel, iron, nickel, titanium, tungsten, molybdenum, and refractory metal compounds.

Performance and Application

Performance and ApplicationSintered stainless steel porous material have excellent corrosion resistance, oxidation resistance, wear resistance, and mechanical properties (ductility and impact strength, etc.). The sintered stainless steel porous material can be used in silencing, filtering and separation, fluid distribution, flow limiting, capillary core, and other fields.

Sintered porous titanium and titanium alloy materials not only have the general properties of metal porous materials, but also have low density, high specific strength, good corrosion resistance, and good biocompatibility of metal titanium with excellent performance, widely used in food and beverage, environmental protection energy, chemical, medical pharmaceutical, electrolytic gas industries such as precision filtration, cloth, decarburization process, electrolytic gas, And to make biological implants.

Sintered nickel powder multiporous materials have the advantages of corrosion resistance, wear resistance, high mechanical strength at high temperature and low temperature, thermal expansion, good conductance, magnetic permeability, etc., which can be used as electrodes for high-temperature precision filtration and rechargeable batteries. Of Monel alloy porous material in the power plant can be used for making seamless water pipe, steam pipe of the filter element, the water exchange and evaporator filtering device, filter elements, sulfuric acid and hydrochloric acid environment of crude oil distillation filtering device, used in water filtration equipment, the nuclear industry used in the manufacture of uranium refining and isotope separation filtration equipment, Manufacture filter elements for hydrochloric acid equipment, and filter element for the slow-temperature area of the hydrofluoric acid system in refinery alkylation unit.

Sintered powder copper alloy porous material has the advantages of high filtration accuracy, good air permeability, and high mechanical strength. It is widely used in pneumatic components, chemical industry, environmental protection, and other industries, such as compressed air oil removal purification, crude oil sand removal filtration, nitrogen hydrogen filtration, pure oxygen filtration, bubble generator, fluidized bed gas distribution, and other fields.

TiAl, NiAl, Fe3Al, and TiNi are widely studied and applied in sintered powder intermetallic porous materials, which synthesize the functional properties of porous materials and intermetallic compounds. Fe3Al porous material can be applied to the direct purification and dust removal of dusty gas at high temperatures, such as energy (clean combustion combined cycle power generation technology and pressurized fluidized bed coal-fired power generation technology), petrochemical, metallurgy, electric power, chemical industry, glass industry, and environmental protection, etc. TiNi porous material has a special quasi-elasticity and global memory effect, which makes it very suitable for human bone implantation material.
