That is a whole lot of silicon mixed in. I believe you are talking about making a hypereutectic piston.

Maybe these guys have some trailings from their mix.

Since you're in the US, have you tried contacting Nelson of Jett for a stick of material? I'm not sure if they do this, but that was going to be my next step when I was looking for it.
