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 Titanium Alloys?
Titanium Alloys in commercially pure Grades 1 and 2 are available in powder form; Grade 2, stronger than Grade 1, finds numerous AM applications in the medical industry due to its excellent biocompatibility with tissue and bone. The most commonly used AM alloy is Ti6Al4V (Grade 5), offering excellent strength and toughness combined with the corrosion resistance, low specific weight and biocompatibility. It’s widely used in aerospace applications and biomedical implants. A higher purity grade--Ti 6AL-4V ELI (Grade 23)—finds use in dental applications.
