Aluminum powder (that is, silver powder), aluminum powder is very lively and will be oxidized soon if it is put in the air, so aluminum is generally gray and not bright.
Aluminum powder is commonly known as aluminum silver powder or silver powder because of its silvery metallic luster. Its chemical composition is actually "aluminum" rather than "silver". Uses: powder coating, ink, plastic masterbatch, printing, imitation gold paper, imitation gold card, gold film, textiles, but it will be oxidized and blackened when used in water-based paints and paints with acid and alkali. It is not recommended to be used in situations where acid and alkali resistance and rainwater combination are needed.
