What is the hardness of scandium on the mohs scale?

No one seems to know how hard scandium is on the mohs hardness scale (believe me i looked everywhere and they all say N/A) but i did manage to find it's hardness on the Brinell hardness scale. On the Brinell hardness scale it is 750 MPa. If you find how hard it is on the mohs scale please revise my awnser to also include that.
