Description
5 pound ingot
This ingot measures approximately 8-3/4" x 1" x 2"/
This is an alloy of 30% Antimony and 70% Lead that is a great source for hardening up your lead or wheel weights and is much easier to melt then pure antimony as we have done the alloying for you. This alloy will melt at around 745 Degrees which should be easy to reach in most small melting pots.
We sell Super Hard based on the percentage of antimony in the alloy. Note: We make no promise on Brinell Hardness of Super Hard, as the crystalline structure of the alloy does not allow us to properly measure it, you would need a special commercial larger ball diameter machine in order to read the hardness correctly.
Lots of great info here about using super hard!

Harden you alloy
I had been using a 5% alloy, then tried lymans #2, which is superior. I used this super hard plus a little tin to alloy all my 5% up to lymans hardness, worked fantastic
