Powder Metallurgy - Advantages of Powder Metallurgy over Conventional Metal Fabrication Techniques

Production of components via powder metallurgy has many potential advantages when compared to producing them via conventional methods, such as machining from billets. Some of these advantages include:

 

1. Huge potential savings in production by using powder metallurgy which is geared towards mass production

 

2. The flexibility to produce compositions not possible by other methods e.g. metals and non-metals, as well as metal-metal combinations

 

3. Powder metallurgy is a near nett shape forming process, meaning that in many cases no finishing operations are requited. Further the dimensional accuracy possible is quite high

 

4. Raw materials easily obtainable and relatively inexpensive

 

5. Repeatability across parts is normal meaning consistent properties and dimensions for components

 

6. The number of operations required to produce a finished part is often less than other fabrication methodologies

 

7. Parts can be manufactured with controlled porosity. Further, it is possible to infiltrate these pores either with other materials e.g. lower melting point metals or lubricants

 

8. The process generates very little scrap

 

9. Potentially very high production rates, especially compared to machining

 

10. Parts can be manufactured with excellent wear resistant properties and friction co-efficients

 

11. Parts have sound and vibration damping properties

 

12. Powder metallurgy can produce geometries not possible by processes such as machining

 

13. Parts have good chemical homogeneity

 

14. Powder metallurgy can also be used for fabrication of magnetic components, as well as controlling magnetic properties to some degree.

 

15. The time taken to take a part from concept to production using powder metallurgy is often quite short which has economic benefits

Shipments of industrial-class 3D printers (priced above $100,000) were up by more than 8% in Q3 2019 compared with the same period the previous year, according to market intelligence from Context (London). This key sector, which accounted for almost 70% of all 3D printer revenues for the period, saw even more impressive shipment growth of 12% on a trailing 12-month basis.“The increase came as a su...

Researchers at RMIT have found that sound vibrations can improve the micro-structure of 3D printed alloys.The team used high frequency sound waves to make the alloys more consistent and stronger than those printed conventionally. Lead author, Carmelo Todaro, highlighted that the method deals with inconsistencies in 3D printed alloys.“If you look at the microscopic structure of 3D printed alloys, t...
