Making Metal Powder MPIF

Making Metal Powder. The first step in the overall powder metallurgy (PM) process is making metal powders. There are four main processes used in powder production: solid-state reduction, atomization, electrolysis, and chemical. Copper is the primary metal produced by electrolysis but iron, chromium, and magnesium powders are also produced

Powder metallurgy Wikipedia

Powder metallurgy (PM) is a term covering a wide range of ways in which materials or components are made from metal powders.PM processes can avoid, or greatly reduce, the need to use metal removal processes, thereby drastically reducing yield losses in manufacture and often resulting in lower costs.. Powder metallurgy is also used to make unique materials impossible to get from melting or
