ATO INSIDE

ULTRASONIC POWDER ATOMIZATION TECHNOLOGY

Ultrasonic vibration technology is used to break molten metal into small droplets, which rapidly solidify into metal powder in an inert gas atmosphere. The metal powder size produced depends on the frequency of the ultrasonic waves, with higher frequencies producing smaller particles and lower frequencies producing larger particles. Factors affecting particle size and distribution are viscosity, density, ultrasonic amplitude and atomizer design. Ultrasonic atomization of metal powder using ATO technology is a process in which metal powder is melted using an electric arc. Ultrasonic vibrations are then transmitted into the molten metal, creating capillary waves. These waves eject metal droplets, which are rounded and cooled before being collected and sorted. The result is almost perfectly spherical metal droplets.

Designed for Precious & Noble Metals

ATO Noble supports efficient atomization of a wide range of precious metals and custom noble alloys, including:

• Gold (Au)

• Silver (Ag)

• Platinum (Pt)

• Palladium (Pd)

• Custom precious metal compositions

This flexibility makes ATO Noble suitable for both standard production and specialized alloy development.
