Title: LOW MELTING POINT METAL OR ALLOY POWDERS ATOMIZATION MANUFACTURING PROCESSES
Abstract:
There are provided low melting point metal or alloy powder atomization manufacturing processes comprising providing a melt of the low melting point metal or alloy through a feed tube, diverting the melt at a diverting angle with respect to a central axis of a feed tube to obtain a diverted melt into an atomization zone of an atomization chamber, and providing at least one atomization gas stream at a velocity of more than 300 m/s and at a ratio of the volume of the at least one atomization gas stream per unit volume of the metal or alloy to be atomized. The process can be carried out in the presence of water within the atomization chamber.
