Powder sintered metal is a metal powder metallurgy processing technology that sinters metal powder into a solid metal billet under high temperature and pressure. In this process, metal powder is heated to a temperature close to its melting point, causing sintering of its particles to form a billet with a certain strength and density.
Features of powder sintered metal include：
High density: Because the metal powder is sintered under high temperature and high pressure, the final metal blank has a high density, which can usually reach more than 90% of the metal.
Good uniformity: Metal powder can be evenly distributed throughout the sintered compact, making its properties uniform.
Ease of processing: Sintered metal blanks can be processed, such as cutting, drilling and welding.
Parts with complex shapes can be produced: Powder sintered metal can produce complex shapes, such as cams, gears and mandrels.
Applications for powder sintered metals include:
Manufacture of metal parts: Powder sintered metal can be used to manufacture various metal parts, such as auto parts, aviation parts, electronic equipment parts, etc.
Manufacture of cutting tools: Since sintered metal has high hardness and high wear resistance, it can be used to manufacture cutting tools such as milling cutters, drills and turning tools.
Fabrication of heat exchangers: Sintered metals can be used to fabricate heat exchangers due to their good thermal conductivity and high strength.
Manufacture of electrode materials: Powder sintered metals can be used to manufacture electrode materials, such as nickel hydroxide electrodes and palladium electrodes.
In conclusion, powder sintered metal is an important metal powder metallurgy processing technology, which has the advantages of high density, good uniformity, easy processing and preparation of complex shapes. It is used in a wide range of applications, including the manufacture of metal parts, cutting tools, heat exchangers and electrode materials, among others.
