They use a fine metal powder squeeze it under somewhat high pressure in a die to form the shape. (Sintering is NOT forging) The powder has a binder in it so when its sintered (heated up to high temp) it binds together. Powdered metal parts are OK but I wouldn't make gears out of it which are under a lot of stress. Would be better off hobbing the gears and then heat treating them but that costs quite abit more than a powdered part. A gear machined from a forging or a solid piece of stock would be a lot better. Tungsten carbide inserts common in the machining industry is a good example of a powdered metal part.

Brazing is more of a term that describes a heat range. For example once you get over a certain temperature you are no longer "Soldering" a part together you are now "brazing" it together. You can braze brass, copper, steel cast iron and etc with the same low fuming bronze brazing rod and a oxyfuel torch.

dstig1 is gaining momentum as a positive member of FTE.
PM is heavily used for gears. That is one of it's strongest applications.

Machining from solid stock is often not as strong due to grain structure issues. For a related example search the interweb on rolled threads vs cut threads.

Many parts that are sintered are also infiltrated with a lower melting metal to fill in the remaining interstices in the PM matrix.

Tungsten carbide is sintered, but is not PM as it is a ceramic. Similar process, but yet different.
