Advantage, Disadvantage, and Application:

The advantage of Powder Metallurgy:

1. The parts can be produced clean, bright and ready for use.
2. Composition of the product can be controlled effectively.
3. Articles of any intricate shape can be manufactured.
4. Close dimensional tolerance can be achieved.
5. Machining operation is almost eliminated.
6. Parts have excellent finish and high dimensional accuracy.
7. There is the overall economy as material wastage is negligible.
8. Metals and non-metals can be mixed in any proportion.
9. A wide range of properties such as porosity, density etc. can be achieved effectively.
10. High production rate can be achieved.
11. Reduced production time.
12. Highly skilled labor is not required.
13. Saving in the material through reduced wastage.
14. Composition structure and properties can be controlled easily.
15. A wide range of parts with special electrical and magnetic properties can be produced.

The disadvantage of Powder Metallurgy:

1. High initial cost of metal powder.
2. Size of the parts produced is limited due to large presses and needed to get required compressing pressure.
3. The equipment used for the operation is costly.
4. Impossibility of having completely dense product.
5. Pressure up to 100 tonnes capacity is used even for a small product.
6. Metal powder is expensive and in some case difficult to store.
7. Some power may present explosion hazards.
8. Dies used must be of high accuracy and capable of withstanding high pressure and temperature.
9. Parts produced have poor ductility.
10. High tooling cost.
11. Difficulty of sintering low melting powder.
12. Poor plastic properties.
13. Necessity of protective atmospheres.
