Does the pump shaft of a magnetic pump have to be made of silicon carbide?

Does the pump shaft of a magnetic pump have to be made of silicon carbide? For corrosive media, the use of silicon carbide is perhaps a last resort; after all, silicon carbide is quite brittle. Then why use shafts made of silicon carbide for non-corrosive media? Using stainless steel shafts would be sufficient
Silicon carbide shafts are used in perfluoroelastomer magnetic pumps due to their corrosion resistance; however, their weakness is low strength. For non-corrosive media, it is recommended to use metal shafts
Sliding bearings are often made of silicon carbide, but this is not absolute. There is also graphite, containing graphite-silicon carbide.
Who said the pump shaft has to be made of silicon carbide? The ones we use here aren’t.
High-density carbon, PTFE, silicon carbide are all available
