Aluminum powder is produced by air atomization process The resulting powder might then be processed further in a ball mill to flatten it into flakes for use as a coating or pigment.
Aluminum powder is used in powder metallurgy to fabricate complex parts. It's a well-developed, cost-effective process that involves die compaction and sintering.
Aluminum powder is normally coated with a layer of aluminum oxide unless the particles are freshly formed.
There are two main types of aluminum powder:
Aluminum powder is used for several applications, including:
