The invention provides a metal propellant storage tank for spaceflight. The metal propellant storage tank for the spaceflight comprises a shell 1 and a metal diaphragm 2. The shell comprises a gas circuit joint 3, an upper semisphere 4, a connecting ring 5, a lower semisphere 6 and a liquid circuit joint 7, wherein the upper semisphere 4 and the lower semisphere 6 are connected through the connecting ring 5, the gas circuit joint 3 is connected with the upper semisphere 4, the liquid circuit joint 7 is connected with the lower semisphere 6, and the metal diaphragm 2 is in butt joint with the connecting ring 5. The overall shell 1 is made of the scandium aluminum magnesium alloy materials whose brand type is 5B70. The metal diaphragm 2 is made of pure aluminum. The invention further provides a manufacturing method of the metal propellant storage tank for the spaceflight. The metal propellant storage tank for the spaceflight solves the problems that the propellant storage tank is large in quality and low in structural efficiency, realizes the light design of the propellant storage tank, effectively reduces the weight of the storage tank, and greatly reduces the launch cost of a vehicle.
