Brinell Hardness..

[gareth96]

I know I could probably find the answer to this if I searched better.. but say you have a soft lead of 8bh, and an alloy of 12bh.. and you mix them exactly 50/50. Will you end up with a 10bh alloy?

the answer is maybe.
if the first is 30-1 and the second is mostly an antimonial alloy like ww's.
you might get a 10 you might also retain the 12.
the final outcome will be based on the players not the bhn of the two alloys.

+1 what runfiverun said. My experience is that the effect of tin is linear. If the 8 Bhn and 12 Bhn both had only lead and tin in them, a 50/50 mix would be 10.

If antimony is in the mix all bets are off. It seems that antimony hardens quite a bit when it is included small amounts. However, the effect of more antimony drops off fairly quickly. With a mix that includes antimony, a 50/50 mix would probably not be 10, but higher.

And of the 12 was wheel Weiss and we water drop the final result it will be well over 12.

BHn is a measure of hardness but tells little about the actual alloy composition. I wpuld far prefer to know the composition of an alloy than to know the hardness. I can modify hardness far easier than I can modify composition.

Smelt a small batch to find out.

Have you read "From Ingot To Target" the book that is offered for free in the sticky section?

The results are best known from shooting and by trial and error. There is no magic here.

Based on my experience combining stick-on WW with clip-ons, probably not. Pure Pb is closer to 5-6 so the BHN 8 metal has been alloyed with something. My guess is that your result will be around BHN 11 depending on the actual composition of your BHN 8 alloy. Your result may vary with casting temp too.
