Powder metallurgy products industry main product classification
Powder metallurgy products mainly include: iron base parts, steel base parts, bimetal parts, powder metallurgy friction parts, soft and hard magnetic ferrite products.It can be divided into powder metallurgy mechanical parts, friction materials, magnetic materials, cemented carbide materials, etc.
Characteristics of powder metallurgy products
Powder metallurgy industry is one of the important basic parts manufacturing industries in the mechanical industry. Its basic manufacturing processes include mixing, pressing, sintering, finishing and post-processing.
Compared with the traditional casting and machining methods, the parts manufactured by powder metallurgy technology have the following prominent characteristics:
(1) most refractory metals and their compounds, pseudo-alloys and porous materials can only be manufactured by powder metallurgy.
(2) as the powder metallurgy method can be pressed into the final size of the billet, without or little need for subsequent mechanical processing, it can greatly save metal, reduce product costs.When products are manufactured by powder metallurgy, the loss of the metal is only 1-5%, whereas it may be as high as 80% when produced by ordinary casting methods.
(3) as the powder metallurgy process does not melt the material in the material production process, it is not afraid of mixing impurities brought by crucible and deoxidizer, while sintering is generally carried out in the vacuum and reducing atmosphere, without fear of oxidation and without any pollution to the material, so it is possible to produce high-purity materials.
(4) powder metallurgy can ensure the correctness and uniformity of material composition ratio.
(5) powder metallurgy is suitable for the production of a large number of products of the same shape, especially for products with high processing costs, such as gears.
To sum up, powder metallurgy has the advantages of low material loss, high product purity, stable product performance and easy scale production.Powder metallurgy can produce materials and parts that cannot be prepared by traditional casting and machining methods.
