Aluminum powder (also known as “silver dust”) is a metallic silver pigment that is often made from aluminum foil. The powder is then ground into a fine powder and polished.

More information about Aluminium Al Powder

Aluminium powder

Aluminium powder

A silver metallic pigment, also known as “silver” or “silver powder”, can be found in the form of. This is achieved by adding a little lubricant or oil to aluminum foil and then crushing the powder into fine powder. Finally, it’s polished.

Aluminum powder in fine quality

Light in weight and high in floating strength, it is strong in hiding potential and excellent in reflecting heat and light. You can make it non-floating after treatment.

Powdered dark aluminium

Many types of explosives can be made with it. You can also use it to manufacture certain kinds of electronic items. A lot of coatings, sealants and adhesives contain aluminum powder. Aluminum powder can be used to make solar cells and other products which carry current. Most solid rocket fuels, including aluminum powder, are made out of this metal.

Aluminium powder

This ingredient is used in sunscreen, lightweight concrete and solar panels. The aluminum ingots are melted in a furnace before being sprayed under high pressure to make fine granular powders. . Two kinds of powder may be made depending on how the atomizing gases are used to blast molten aluminum out the nozzle head.

Aluminium pigments are used for everything from inks and graphic design to protective coatings on bridges and buildings and automotive coatings. A majority of the aluminum pigments are made from aluminum powder. The mill should be filled with mineral spirits, acid lubricant, and aluminum powder. As the mill revolves, the aluminium paste is pushed by the moving balls into the chamber. This causes the aluminum paste to flatten upon impact. The resulting flakes are then broken.

How does aluminum powder get made?

1. Melt extrusion method

This involves heating and extruding the other components (resins, etc.). Use a screw extruder to mix the powder coating with metallic pigment. While metallic pigments as well as powder coatings are possible to be combined, it’s not feasible to choose metallic pigments that melt in high viscosity. A grayish metallic effect is also produced when the metal powder is processed by this method. This is why this process can be only used for producing hammer dust.

2. Dry blending

You add dry metal pigment powder to the pulverized coating of powder and blend it using a mechanical mixer. The dry blending technique has the advantage that it does not involve intense mixing. It prevents deformation of flake metallic pigments. Additionally, loose pigment/resin blends are very compatible with metallic pigments. This allows for a better glitter effect. However, this technique can lead to separation of metal pigments and resin particles when they are processed with automatic spraying equipment.

3. Methode de supplémentary fixation (bonding process).

The metal pigment and the powder coating can be dry-mixed together and then heated simultaneously to just reach the hardening point. The metal pigment can then be attached to the surface or powder of the adhesive resin. This will prevent it from being made. It is possible to separate the resin powder and metallic pigment during recycling. It’s the most well-known bonding law.

4. Jet milling method

Supersonic airflow pulsed pulverization is the method used. To produce fine aluminum powder, the JZDB nitrogen shielded-airflow pulverization classifier is employed.

Aluminum powder:

In the crust of Bauxite, aluminum is a common metal element. Aluminium is separated from the bauxite by a chemical process called Bayer. This silver medal is non-toxic, non-magnetic and soft to form. There are many ways to use aluminum, whether it is in solid or powder form.

It’s explosive

Because aluminum powder is very flammable it can be used for pyrotechnic display. Aluminum powder can burn very brightly, and produce flashing effects that vary depending on the grade of powder used. Aluminum powder can also be used in an identical way to explosive compositions used in commercial mining. Aluminum powder was used in the making of camera flashes in the past when photography was just beginning.


The aluminum powder is used often to produce metallic silver pigments. Sometimes, it is sold in shops as aluminum bronze. Flake aluminum powder is usually coated with either talc, or another compound that decreases its reactivity to make aluminum bronze. Aluminium powder pigments can be used to coat electronics, packaging, and automobile industries. You can also make thick pastes from aluminum powder, and then coat them on photovoltaic panels to make them more conductive.

Use fingerprint powder

For fingerprint formation on smooth surfaces and non-porous surfaces aluminum powder is used often at crime scene scenes. According to the British Home Office aluminum flake is the most efficient fingerprint powder on glass. Alabaster flake powder is able to provide contrast on any colored surface, except silver. To form prints, apply a little aluminum powder to the surface. This is done using a Zephyr brush that’s made with fine glass filament.

Rocket fuel

The main component of rocket and missile fuel is aluminum powder. Because of its availability and high reactivity, aluminum powder can be easily used to provide large amounts of thrust, at relatively low costs. This is how aluminum powder was used to make the NASA solid rocket motor.

Aluminium Al powder Storage Conditions

It is important to keep this product in a dry, cool environment.
