Распыленный алюминиевый порошок
Высокочистый распыленный алюминиевый порошок — это высокоэффективный металлический порошок, получаемый методом распыления на воздухе, в результате чего образуются частицы неправильной формы с контролируемым распределением по размерам. Он широко используется в горнодобывающей промышленности, производстве взрывчатых веществ, термитной сварке, металлургии, химической промышленности, производстве пигментов и энергетических составов.
Ассортимент продукции включает в себя крупнозернистые, мелкозернистые, сверхмелкодисперсные и пылевидные порошки, каждый из которых оптимизирован для конкретных промышленных и пиротехнических применений.
