What is Atomized Aluminum?

Atomized aluminum is a type of aluminum powder that is produced by atomizing molten aluminum. Atomization is a process of converting a liquid into a fine mist or spray. Atomized aluminum powder is typically spherical in shape and has a very small particle size, ranging from 10 to 500 microns.

Atomized aluminum powder is produced using a variety of different atomization processes, including:

• Centrifugal atomization: In centrifugal atomization, molten aluminum is fed into a rapidly rotating disk. The centrifugal force causes the molten aluminum to break up into small droplets, which are then cooled and solidified to form atomized aluminum powder.
• Pneumatic atomization: In pneumatic atomization, molten aluminum is sprayed through a nozzle using a high-pressure gas stream. The gas stream breaks up the molten aluminum into small droplets, which are then cooled and solidified to form atomized aluminum powder.
• Water atomization: In water atomization, molten aluminum is poured into a stream of water. The water quenches the molten aluminum and causes it to break up into small droplets, which are then cooled and solidified to form atomized aluminum powder.

Atomized aluminum powder has a number of unique properties that make it ideal for a variety of applications. These properties include:

• High purity: Atomized aluminum powder is typically very pure, with a purity of over 99%. This makes it ideal for applications where high purity is required, such as in the electronics industry.
• Fine particle size: The fine particle size of atomized aluminum powder gives it a high surface area. This makes it ideal for applications where a high surface area is required, such as in catalysis and pyrotechnics.
• Spherical shape: The spherical shape of atomized aluminum powder gives it good flowability and packing characteristics. This makes it ideal for applications where good flowability and packing are required, such as in powder metallurgy and powder coating.

Atomized aluminum powder is used in a wide variety of applications, including:

• Electronics: Atomized aluminum powder is used in the electronics industry to produce aluminum foil, capacitors, and other electronic components.
• Automotive: Atomized aluminum powder is used in the automotive industry to produce aluminum castings, such as engine blocks and cylinder heads.
• Aerospace: Atomized aluminum powder is used in the aerospace industry to produce aircraft parts, such as wings and fuselage panels.
• Construction: Atomized aluminum powder is used in the construction industry to produce concrete admixtures, lightweight concrete, and other building materials.
• Pyrotechnics: Atomized aluminum powder is used in pyrotechnics to produce sparks and bright white light.
• Other applications: Atomized aluminum powder is also used in a variety of other applications, such as food additives, pharmaceuticals, and personal care products.
