Powder metal parts are the products of the process called powder metallurgy. This process uses fine powdered materials, and obtains the desired shape through pressing or compacting. After which, the compressed material is heated under controlled temperature to bond the powder metal parts through sintering. Powder metal parts are a cost-effective alternative as compared to other applications in metallurgy because it provides higher strength to the material. Likewise, through modern production technology, it is expected that the powder metal parts like bronze, brass and steel have achieved powder metal densities. Thus, materials that undergo the technology of precision powder metal offer the following advantages:
1. Powder metal parts are cheaper in cost.
2. It reduces the need for secondary machining operations.
3. Powder metal parts can match the specific requirements of the materials.
The application of the powder metal parts is highly efficient. Some of the products that use powder metal parts include metal switches, gears and sprockets, transmission components and automotive engine, surgical tool components, housings, conveyors and door closers, valve plates, plumbing equipment and pistons.
Likewise, powder metal parts are also beneficial to transmission components such as clutch plates, brake gears, slides, oil pump rotors and gears. In the same manner turbine hubs, torque converters, counterweights, bearings and cam sprockets are also using powder metal parts.
On the other hand, powder metal parts are also created through sintering. They are necessary in the development and operation of appliance, automotive, audio equipment, and precision machinery. According to research, 41% of the automotive industry is using powder metal parts as well as 21% of the industrial machinery. The 5% of other industries are not using powder metal parts instead they use other applications.
The process of using aluminum in making powder metal parts is similar with other materials used in powder metallurgy. The first step is the material selection of different grades of powder metal aluminum. The powder blend used in making powder metal parts also contain additives such as magnesium, copper, silicon and small percentage of lubricant.
The next step is the pressing in which the powder metal parts are pressed through conventional pressing using conventional tools made of steel or carbides. The ejection and compaction pressures used in aluminum are lower as compared to ferrous powders because aluminum is soft. Using lower pressures is advantageous because it makes the powder metal parts to become ductile thus reduces potential tool breakage.
The last step is through sintering that is the most important in manufacturing powder metal parts. When aluminum is used in sintering it saves energy because aluminum requires lower temperature in creating powder metal parts.
Moreover, using aluminum in manufacturing powder metal parts provides winning combination. This material is widely used in powder metallurgy because of its exceptional attributes aside from the specific properties of aluminum. Good appearance is obtained in using aluminum in making powder metal parts because of its natural appearance.
Likewise, it is also possible to make decorative finishes in the metal parts especially for cast aluminum alloys that are applied in aluminum powder metallurgy. The appearance is enhanced through etching and mechanical finishing in achieving color and textures. Likewise, electroplating and painting can be used in improving the appearance of the powder metal parts.
Aluminum is one of the materials used in making powder metal parts. Most metal manufacturing companies are using aluminum powder metallurgy because this material has extra ordinary properties once converted to metallic state. Aluminum is used in powder metal parts because it is light in weight and high resistance to corrosion. The Al-Mg-Si alloys are extremely resistant to corrosion as compared to other ferrous-based products. However, the powder metal parts can be coated with chromate or it can be anodized to increase the resistance to corrosion. For water resistant application, hard type anodize should be applied.
Likewise, through heat treatment aluminum becomes more stronger as well as excellent conductor of electricity and heat. In addition, when this material is used in metallurgy the powder metal parts become non-magnetic thus becomes useful property with sensitive electronics. In the same manner, it also shows good machinability and good response to different finishing processes.
Additionally, using aluminum in powder metal parts is advantageous in machining operations such as smooth surface finish, high cutting speeds and superior tool life. Likewise, aluminum also facilitates various bonding and joining techniques for powder metal parts. This means that powder metal parts made from aluminum powder can be easily fastened even by simple adhesive bonding or by using threaded fasteners. Aluminum powder metal parts offers excellent thread characteristics of 90% density level. Since aluminum has ductility property the powder metal parts have higher density of self-tapping fasteners.
The performance and mechanical properties of aluminum powder metal parts is also at par. The tensile strength of the aluminum powder metal parts varies according to the thermal treatments, sintering practices as well as the density of the alloy. However, further processing like cold or hot forming can produce properties just like the wrought aluminum materials. Indeed, the mechanical properties of the aluminum powder metal parts are significant in selecting materials to be used in creating powder metal parts.
