Hi everyone, I have just a few questions about adding superhard to my alloy.
Rotometals says I need about 745 degrees to alloy it to my lead. I didnt realize that and was running my pot at 700 degrees, just trying to get things setup for casting later this week.. When it cooled it looks like the SH floated to the top.
I used the excel calculator here, and was adding about a half pound of SH to some lead/tin in hopes to get a 12bhn.
Will it mix back in at 750, or did I ruin this little batch?
And finally, once its been melted and mixed in, do I have to keep my melt at 750, or can I back off to a more reasonable 700?
Thanks in advance.
