Isn't indium around £400 per kg?
Yeah I didn't notice the amount dropped from 100g prices for the others to 10g prices for indium.
Also on further research most of these have very high mps except molybdenum.
The others much higher than Al and Mg anyway.
Barring molybdenum they are all higher than Fe and Cu too.
Was just a poorly thought through curiosity question.
I think Ni comes next after Cu so you would most likley need a very hot mix to more than likley just get another white.
However I may just be talking bollocks cos I currently know nowt.
