Just wanted to check with my more learned colleagues on this issue....
I know when I was with the aluminum mill, our chemical certifications for aluminum alloys was based on volume and not weight.
Are lead alloys based the same? If so, Sn weighs 57% what lead does.
(according to a website periodic table). That is a sizeable difference.
This may be moot, but I was curious.
Myself, I typically add Sn if mold is not filling out to suit me.
