Compared with other types of high-temperature alloys, niobium alloys 521 has advantages such as low density, high specific strength at high
temperatures (600-1600℃). Nb 521 owns excellent cold, hot forming properties and good weldability. They can be processed into thin-walled and complex-shaped parts and are used to manufacture components such as the thrust chamber extension of attitude control/orbit control engines for rocket engines, satellites, spacecraft, and missiles. They are one of the important nominated materials for aerospace structural components.
