Interestingly the article switches back and forth between “hard as bone, tough as aluminum” and “hard as aluminum tough as bone”
Neither aluminum nor bone are very hard on the mohs or Rockwell scales though, so I assume toughness is the main desirable attribute.
- ummonk 5y agoFrom some quick Googling (no, I don't know the hardness of bone off the top of my head though having worked with it I can say it's quite soft just like aluminum), it looks like aluminum and bone aren't that different in hardness or toughness, with aluminum alloy being somewhat harder and tougher at the expense of higher density.
