Buddy, good question. I have found a reasonable solution that circumvents the use of tungsten. I call it 'Poor Man's Tungsten' and use non-lead wire tucked under whatever bead you might be using for the particular fly you're tying.
Here is the link to a recent Fly of the Week I presented that shows how simple it is to do this without the added expense of using tungsten beads:

As for other tungsten products such as wire, etc. I haven't found nor heard of any such products. If anyone does know of this, let us all know.
Thanks for binging this up, Buddy.
Kelly.
