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!

    Very pleased with this purchase. I believe that the price was very reasonable and my package shipped more quickly than expected. I was also glad to find that Rotometals has warehouses around the country, which means to me a reliable supply for future purchases.

    Super hard is the best thing that's come along for casters in many years Now I can use that pile of soft lead I've had for 40 years

    Super Hard Alloy is the perfect mix for my application. RotoMetals is a phenomenal company to deal with. The prices are great, customer service is great, and speed of shipping is even better. My last order with Super Hard showed up too fast, believe it or not.
