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!

superhard alloy
effective source of antimony; weights of ingots were accurate and fair; expect this to work well for casting bullets

Excellent Allow, Superb Quality
I add this to pure cleaned salvaged lead along with tin to make Lyman #2 (92Pb, 6Sb, 2Sn) alloy for cast conical bullets. It works great and the alloy achieves the proper Brinell Hardness Number 14.

A must have
I add one pound of this to pure lead along with linotype to get the hardness I'm looking for.

Helps Convert Pure Lead to Bullet Alloy
Received 5.05, 5.09, and 4.98 pound bars; ordered three. Items as described and I have used these in the past, along with tin, to make casting alloy from excess lead from stick on wheel weights and range scrap. One 5# bar with roughly 40-45# of lead seems to get a nice pistol bullet alloy: so 45-50# of alloy per bar.

Super hard alloy ingot
This is great stuff. I used an ingot of super hard to make up a batch of #8 alloy from the LASC super hard formulas page. One ingot of super hard produced 33.75 pounds of BHN 13 alloy. This can be water quenched for rifle bullets, or cut 50/50 with pure lead for pistol bullets.

Super Hard Alloy
This should work great for mixing with all the lead pipe and solder I've gotten over the years

Really great product
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.
