avartana metal powdersare produced byvacuum inert gas atomizedand cooled in argon/nitrogen inert gas. This process allows avartana metal powdersto produce spherical, not oxidised particles with a homogeneous chemical com- position. Powder is sieved using ultrasonic sieving to obtain a precise grain distribution according to the different applications for base metals like nickel, cobalt, hard facing /plasma transferred arc(pta) powders/additive manufacturing powders/thermal spray powders.etc
self-fluxing alloy powders are a type of thermal spraying (welding) materials which have functions of self-deoxidization and self-slag formation when melting. The nickel-chromium- boron-silicon series of self-fluxing alloy powders have been successfully used for equipment manufacture and maintenance in the metallurgical, petroleum, chemical and machinery manufacturing industries. Self-fluxing alloy powder can be applied by spraying or welding using commonly available oxygen-acetylene equipment. During thermal spraying or welding, the molten alloy forms a metallurgical bond with the substrate surface. Coatings thus formed are very dense, wear and corrosion resistant up to medium temperatures and adaptable for hard facing gears, dies, valves and other mechanical components vulnerable to wear.

AVARTANA metal powders for additive manufacturing (3D printing, rapid prototyping) are characterized by a spherical morphology and high packing density, which confer good flow properties. For powder bed processes these are essential when applying fresh powder layers to the bed to ensure uniform and consistent part build.
For blown powder processes good flow ensures uniform build rates. Tight control of the particle size distribution also help ensure good flow ability. Low oxygen powders result in clean micro structures and low inclusion levels in the finished parts.
Particle size distributions
Avartana metal powders for additive manufacturing (3D printing, rapid prototyping) is available in a wide range of particle size distributions that are tailored to the individual additive manufacturing systems. They can also be tailored to the particular requirements of the end application, both in terms of mechanical performance and surface finish.
