Sintered Metal

Sintered metal parts are solid metal products made via a powder metallurgy process that features a sintering step, as opposed to a metal injection molding step. In short, sintering presses metal powder into a coherent mass without altering its shape by heating it below its melting point. Sintered metal parts are used in a wide variety of industries, including automotive engineering, military and defense, lawn and garden, food and beverage, computers, electronics and hardware. Examples of sintered metal parts include bearings, bushings, frangible shotgun shells called breaching rounds, steam filters and structural parts, such as wicking structures in heat pipes.

All powder metallurgy processes begin with the creation of metal powder from solid metal stock shapes or bars. This may be achieved a number of different ways, among them centrifugal disintegration, chemical decomposition, grinding and atomization. Most often, manufacturers choose to convert solid metal into powder using atomization. This is because, by separating molten metals into separate particles that then freeze into solid form, this process can effectively process nearly all metals. While powdered, a pure metal may be enhanced with another metal, to make an alloy, or with lubricant additives. Once a metal is turned into powder, it goes on to the forming portion of the process. During this step, the powdered metal is poured either into a mold cavity or a die prefabricated in the shape of the desired part. Once inside, the metal is compacted under large amounts of pressure at room temperature until it becomes a solid shape. Note that exact amount of pressure applied to the metal determines the malleable of the finished piece. After the second step is complete, the metal mass is removed from the mold and placed inside an extremely hot furnace. This part of the process is known officially as sintering. During sintering, the particles of the metal fuse together but do not melt, as the furnace is not heated all the way to the metal’s melting point. The result of sintering is a strong, porous and rigid metal piece.

After a part has been sintered, manufacturers may choose to alter it using secondary processes. One of the most common alterations of sintered metal parts is a change in porosity. This is because the porosity of a part determines both its gas and liquid flow levels. To alter porosity, manufacturers may use a few different sealing techniques, including impregnation with a plastic or oil resin, steam filtration or infiltration with a metal that has a lower melting point. Other secondary processes that sintered parts may have to undergo include those related to heating, sizing, deburring or machining. Bushings and bearings in particular, as well as other parts with very close tolerances, often must go through secondary sizing procedures.

Sintered parts can be created using all sorts of metals, including: aluminum, brass, bronze, copper, nickel, stainless steel and titanium. Furthermore, some metals that have very high melting points cannot realistically be machined unless they are machined. Examples of those metals are: carbon, molybdenum, osmium, rhenium, tantalum and tungsten. In addition metal sintering, there are a few other types of sintering. These include: liquid phase sintering, electric current assisted sintering, electro sinter forging, spark plasma sintering, plastics sintering, pressureless sintering and microwave sintering. On top of the fact that it can nearly universally be applied, there are a number of reasons to create solid metal powder parts through sintering. First, sintering produces very little waste, with approximately 97% of the original material used to create a part ending up in the finished part. This lack of waste is not only good for the environment, but it is also cost-effective, especially during the fabrication of high volumes of metal parts and/or costly metal material parts. Also, the sintering and powder metallurgy processes allow manufacturers to produce parts with relatively close tolerances, even in large quantities. Furthermore, sintered metal parts can be fabricated with high levels of repeatability. In addition, sintered metal parts display high levels of both magnetism and porosity, the latter which naturally dampens sound. Lastly, but most certainly not least of all, sintered parts are durable and, often, cannot be produced using any other method. To find out more about sintered metal parts and how they may serve your application, reach out to an experienced powdered metal part manufacturer. For the best advice, talk to one of those manufacturers listed on this page. All of the companies with which we partner are knowledgeable, reputable and ready to assist you in your endeavors.
