I'm trying to create an alloy with a density of silver without the cost of silver for a fine tuned calibration device

I would have used silver 5 years ago but with the price of it nowadays I am looking for an alternative

Thank you for your response, maybe someone else can help shed some light on this conundrum as well! :)

Following Rich's lead, the alloy for Nickle/Silver aka German Silver may work as there is no actual silver. It may also look better when finished than anything with lead in it.

I have worked with leaded iron so the temperature differance must be controlable but I am not a metalurgist.

Do you have a concern on final appearance as some alloys can be ugly and poorly machinable?

German silver doesnt work because neither of the 3 additives have a larger density than silver itself.

Needs to be machinable and will be nickle plated afterwards

The material itself cannot be magnetic.. a possible combination would be a Lead and Bismuth alloy but It isnt very desirable .

Is it possible to alloy tungsten and copper?
15% Tungsten 85% copper?

Or how about 50% Thalium 50% Copper?

Thanks

Disregard the Tungsten Copper.. Their boiling/melting points overlap so that wouldn't work.

Do you have to have an alloy? I am thinking that it would be much easier to do something like a mokume mixture. You could still get the density you want and yet not spend a fortune making a custom alloy. If the objective is to save money creating an exotic alloy seems a poor pathway.

Tungsten shot is available at reasonable prices that has a density of 15 to 16 g/cc (vs 10.5 for silver). Could you mix that with copper shot or some other lighter shot and solder it together?
