What is blackhead aluminum?
Our Indian Blackhead Aluminum Powder is used for paints, pigments, thermite compositions, reactive rifle targets, and pyrotechnic compositions. The performance of our powder is identical to the famous Eckart 5413H German Blackhead, and it is available here at a lower price than Eckart 5413H.
What do you use aluminum powder for?
Aluminum powder is used in the production of many types of explosives and fireworks. It is also employed in the manufacturing of certain types of electronics. Powdered aluminum is included in many paints and sealants.
Why does aluminum powder explode?
Finer particles burn readily when their ignition point is reached, and tend to ignite the coarser particles as well. In the case of aluminum, an explosion can result if ignition occurs while the particles are suspended in air as a dust cloud, since the burning extends from one particle to another with extreme speed.
How can I make Aluminium powder at home?
Grind the foil in a coffee grinder using short bursts. Place the pieces into the grinder, secure the lid, and grind the foil. Check the temperature of the aluminum frequently. If the aluminum is getting warm, take a break to allow the aluminum to cool and prevent combustion of the powder.

Is it safe to vacuum aluminum dust?
Aluminum dust can also cause a violent thermite reaction if it comes into contact with some ferrous metal dusts if the right conditions exist. The only correct way is to vacuum conductive metal dusts is with an Immersion-Separation Vacuum that pulls the conductive metal dust into a bath of water or mineral oil.
