What Did I Just Get From My Dross?
I have a large stainless bowl that I use when I melt wheelweights, scrap etc to hold the dross. I was looking at it and noticed metal so I decided to remelt and pour some ingots assuming I wasn't paying close enough attention or stirring in enough sawdust. I got 4 bright and shiney ingots and nothing but dust left over on this secong attempt.
When I put my Lee tester on one it came out
7.7 BHN.
Lead is 5, tin 7 bhn and antimony 50 bhn or so. I expect them to harden a little more and with this in mind anyone care to take a guess?
Tin with a little antimony? I just cast some boolits from 2 containers. 1 COWW and one PB for a 50/50. After 2 weeks their BHN is 14.7 so obviously something not right there. :-(
