As the name would suggest, aluminum powder is simply aluminum in powder form and is created using flakes of aluminum. It is most often used in a multitude of explosives and fireworks, and is also used in the production of different types of electronics. In addition to those uses, it is found in a lot of different paints and sealants on the market as well.
If there are products that are designed to carry an electrical current, such as a solar panel, you are likely going to find aluminum powder inside of it somewhere. The reason aluminum powder is so popular, especially in explosives, is because it’s much safer and easier to handle than its alternatives. In addition to the safety aspect, aluminum powder combined with mixing other compounds can help produce some spectacular and varied effect when used in fireworks.
