What are Metal Powders?
Metal Powders for additive manufacturing, available in numerous alloys including those of aluminum, titanium and nickel, must be of consistent size and shape, as high-quality closely packed, spherical particles of similar size are critical in order to achieve optimum material flow rates and object density. For optimum performance, metal powders for AM are manufactured using gas or plasma atomization.
What are Stainless Steels?
Stainless Steels, which differ from mild or carbon steels by their high chromium content (a minimum of 10.5 percent carbon by mass) are available in numerous grades as powders for AM. These include 316L (used in aerospace, oil and gas, medical and food-processing applications); 15-5PH (aerospace, petrochemical and chemical industries); and 17-4PH.
