With 10c and 1$ so close in size keeping the colours different would be practical to avoid mistakes at the til. So using the same alloy that the 1$ is out . It also doesn't make it any cheaper than it is now to produce .
I imagine a total copper coin is not a popular option for cost and strength again .
That leaves aluminium and stainless both cheaper than copper / nickel / bronze - ali would be the go for lightness and discernibility - but may be easily damaged by the heavier/harder coins .
