What is VIGA Technology and Advantages of VIGA Powders
- VIGA = Vacuum Induction Gas Atomization.
- Melt under vacuum/inert gas, atomize with high-pressure gas
- Rapid solidification to forms spherical powders
- Superior Purity of Powder : Low Oxygen Content
- Excellent Sphericity and Flowability
- Tight Control of Particle Size
- Better Surface Finish and Density in Final Parts

Fisher Sub-Sieve Sizer
To ensure that our Metal powders meet the exact requirements of advanced manufacturing, we use the Fisher Sub-Sieve Sizer which employs the air-permeability principle: a steady stream of dry, filtered air is passed through a compacted powder sample, and the resulting pressure drop is measured using a manometer—this reading is translated into the Fisher Number, a measure of the average particle diameter.
