Aluminum powder for solid propellant
Category
Aluminum powder for solid propellant.
Aluminum powder is an important raw material in solid propellants. As a combustion agent, it has been widely used in solid propellants on a large scale, showing significant advantages such as high calorific value of combustion, low oxygen consumption, and high measured specific impulse. Huayixing solid propellant special-purpose Luen is produced in strict accordance with GJB1730-93 "Specification for Extra-fine Aluminum Powder", and the product quality is stable and well received by users.
