S. no.
Method
Range of size and shape
Advantages
Disadvantages
1
Stir casting
Larger size and extensive range
Low cost, less reinforcement damage, and very high metal yield (>90%)
Vol. fraction range up to 30%
2
Squeeze casting
Limited by preform shape, up to 2 cm height
Relatively expensive and volume fraction range up to 45%
Serious damage to reinforcement, meager metal yield
3
Powder metallurgy (PM)
Controlled size and a wide range
Very high metal yield and volume fraction range up to 30 to 70%
