    Default Mohs Scale for Pewter (Antimony)

    I'm wondering if anyone knows the Mohs Scale rating for Pewter alloyed with Antimony. I can find tin alone (1.5 - 2.5) but the whole point of adding the copper to pewter is the hardness

    Modern pewter contains tin copper and antimony. This source says the Moh's hardness is 3.
