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!

    Really great product

    Posted by Marshall on Feb 23rd 2021

    I've been using this alloy for years to get hardball alloy from wheel weights. I cut 1lb chunks from the ingot using a wood cutting bandsaw. Recipe is 7.5 lbs of rendered clip on weights, 1 lb of superhard alloy and 400 grains of 63/37 high tin solder. The alloy is used for casting .30 carbine bullets from NOE mold, 120 grs round nose with gas check. 13 grs of lil gun drives this bullet at 1900 ft/sec and 3" groups at 100 yds.

    Super Hard Alloy

    Product works exactly as described. But I could not believe that an order placed on a Tuesday morning, would be received on Wednesday afternoon, during the week of Christmas!

    70/30 Super hard

    I mix this with pure lead at a 4/1 ration of lead to super hard, plus 2% tin. This tests at 12.5 -13.0 brindel hardness. I cast .355, .401, 451 and .308 for pistol and 300 BLK. These all work very well for falling steel matches. I just ordered another 20 lbs.

    Great product. Perfect for casting higher FPS rounds.

    This is the best thing to add to existing lead/tin alloy, to give that little bit extra to bring it up to the hardness you.

    I recast this into 1/2 lb ingots in order to achieve the alloy hardness i want.

    Super hard alloy

    product seems to be just as advertised. Seller shipped quickly and product arrived with no issues. Have not used the alloy yet but see no reason to be concerned.

    super hard alloy works great but something seems strange

    Posted by william j pollock on Jul 2nd 2020

    Ok check this out 5 pounds of super hard and one pound of antimony are usually about the same price within a couple dollars or so. So when you buy super hard there is actually 1.5 pounds of antimony in that 5 pound ingot plus 3.5 pounds of lead. That's like getting four pounds of metal for free or Roto Metals is charging way to much for antimony. But really it is a good product much easier and cleaner than alloying the antimony yourself.
