Can some one with a block or bullet of "certified" 16:1 lead tin alloy tell me what the Cabine Tree lead hardness tester should read on the dial? My home made mix is showing a softer ratio. Also is a Brinell value of 11 correct for this?
thanks

KW,
I can't tell you what the Cabin Tree hardness tester should read but my cast bullet alloy calculator says 16:1 has a Brinell hardness value of 10.53. I hope that helps.

Approximately . 070 plus or minus a couple thousands.
Make sure the rod between the sample and dial indicator is lubed if it's an older unit.

Just rec'd this new tester, so of course questions:
That chart does not specifically show 16:1, only shows values for 10, 20 and 25:1. A .070" dial travel puts it in the 20:1 range? Four more thou. travel and you are at 10:1........room for interpretation since its so sensitive.
Texas Mac thanks for the Brinell value

Re: 16:1 Alloy tester dial reading
It should repeat on the same alloy. That is the key. If your alloy is reading . 070 and it's working for you, make your next alloy . 070.
This was never a industrial grade instrument. It's relative, but, it WILL repeat which is the key.
