Aluminum Powder ( Flake )
is a highly flammable powder created by grinding aluminum into fine grains of material. It is one of the tools utilizer in various applications of pyrotechnics, including the creation of fireworks displays.

2. Application ( for firework )
Aluminum powder is one of the most often used fuels in pyrotechnics. A wide range of effects are possible with different types of powder, with differences in particle size, shape and impurities. The finest powders (e.g., Star Molecule) can be ‘airfloat’, and are commonly used in flash compositions. Fine aluminum is also used in hobby-rocket fuels. Courser powders are generally used for sparkling effects. With these larger particle aluminum powder types, many effects such as flitter, glitter, firefly and snowball can be achieved.

6. Fire Fight Method
Since it is almost impossible to extinguish a large aluminum powder fire, the fire must be controlled in its incipient stage.
Aluminum powder fires on reasonably flat surfaces may be controlled by blanketing the fire with a Class D dry extinguishent or ringing the fire with a dam of dry sand. This should be done with great care to avoid disturbing the powder and creating a dust cloud. Even a minor dust cloud may explode violently. Long handled shovels or scoops of non-sparking material should be provided for the application of dry extinguishing agents.
A properly blanketed or ringed fire will develop a hard crust of metal oxide which will ultimately exclude enough oxygen to cause self-extinguishment. After dispensing the extinguishing material, leave the area, close all doors leading to the area and seal them with sand. All fans and machinery, including dust collection systems should be shut down. The area should not be reentered until combustion has stopped and the material has cooled.
Water must not be used to fight an aluminum powder fire since water reacts with hot aluminum powder to produce hydrogen. Also, the force of a water stream could suspend the aluminum powder to form a dust cloud.
Where Class A, B, or C fire hazards exist in powder areas, extinguishers suitable for use on such fires must be labeled “Not for Use on Aluminum Powder Fires.”
