powders are expensive and sometimes difficult to
store without some deterioration
Equipments
cost are high
Some
products can be made more economically by
other methods

to achieve adequate strength in the melting but unsintered
to achieve adequate strength in the pressed but sintered
What are the advantages of powder metallurgy
Low labor cost
Large scale production
Low melting point
Minimizing machining
