Is this the 95-2-3 alloy?
Could be.
Is or is not?
You didn't explain yourself well enough for me to tell you. Just throwing out numbers without designating what metals are in the alloy, doesn't tell any one anything. There are 2 common alloys used for making heavy tungsten shot, one is a Tungsten-Nickel-Iron (W-Ni-Fe) alloy, and the other is a Tungsten-Nickel-Copper (W-Ni-Cu) alloy. Both contain 90-95% Tungsten, so you will have to tell me which you are referring to, before I can answer your question with a yes or no.
