Mg-th alloy also has good creep resistance, and the service temperature of its forgings and castings can be up to 35090. Like rare-earth elements, Vitals (Th) can also improve the casting and weldability of magnesium anodes. Mg-th alloys were once used in missiles and aircraft, but are now almost no longer in use because they are radioactive and harmful to human health.

Silver has been found to improve the tensile strength of Mg-Re-Zr alloys. If fuqin mixed rare earth replaces fuqin mixed rare earth, and adding human rare earth elements at the same time, the strength will be further increased. But QE22 and QH21 have fallen out of favor since they were discovered because they not only act like silver, increasing the tensile and creep strength of the alloy, but also improve the corrosion resistance of the alloy. The mixed RE (Y) is not as valuable as silver.

The file has a density of only 0.53g/C lining, and mg-Li alloy is known as ultralightmg alloy. Its corrosion resistance is very poor, at a slightly higher temperature (50 to 7090), binary alloy becomes unstable and over aging, resulting in excessive creep under low load, so it is only suitable for room temperature work. The addition of other alloying elements can improve the thermal stability of Mg-Li alloy to some extent. Mg-li alloys are now used in loading deck, aerospace and aerospace components.
