Sc has been used in bike frames (bicycle, not motor) for more than a decade now and I know that one Taiwanese manufacturer simply makes all of his frames using Al Sc. He's got two lines, one very expensive and branded as containing that lovely metal and another no name line. He's found that what he saves on the welding costs so overwhelms the cost of the Sc (which is high, $4,000 a kg for the oxide at present, maybe $5 to $10 on the materials costs for a bike frame) that it's cheaper to use it even when he can't charge a premium for its use. The no name line is thus, in metallurgical terms, exactly the same as the high cost one. So we do have some at least real world information that this might be a good idea.

Don't buy that expensive scandium frame

Interesting.............
I'm guessing anything labled up as 6001 6061 7001 etc has to be that aluminium alloy though? So presumably this only applies to the manufacurers own brands of aluminium?

I recall On One went from Scandium to AL7046 with the Scandal.At the time they claimed it made no difference to the ride quality.
Though I note they didn`t change the name to the AL7046-dal.......Posted 6 months ago #
