Aluminum-beryllium intermediate alloys are used in the melting of aluminum and magnesium alloys to improve the cleanliness, flowability, and corrosion resistance of magnesium and aluminum. They protect against oxidation and burning of magnesium and aluminum, reduce oxidative losses of elements, refine grain structure, and enhance strength. 

Known as beryllium-based aluminum alloys (with a beryllium content of approximately 62%), they conserve beryllium resources compared to metallic beryllium. Due to their outstanding performance, they are widely utilized in the manufacturing of missiles, rockets, supersonic structural components, and aircraft brakes. They can substitute for metal beryllium applications in most areas and possess strong competitive advantages and promising development prospects in the aerospace field.
