What is powder metallurgy?

Powder metallurgy is a process in which metal powder is used as raw material, and parts are obtained through molding and combustion.

Advantages: save the cost of raw materials and simplify the processing technology

Disadvantages: traditional processes will reduce the ductility of the product, while special post-treatment processes will increase its manufacturing cost.

The circulator cavity made by powder metallurgy process cannot be completed with three bottom holes and internal thread at one time, so the machining process is needed, which will increase its manufacturing cost, and the ductility is not as good as the traditional process.
