We use powder metallurgy to avoid or greatly reduce the need to use metal removal processes, thereby drastically reducing yield losses in manufacture and often resulting in lower costs. It is easy to obtain and inexpensive.
Powder metallurgy is a near-net-shape forming process, therefore the dimensional and accuracy are quite high.
Powder metallurgy can also produce geometries not possible by processes such as machining.
The production time of using powder metallurgy is quite short which has economic benefits.
