Basic Rules for Hardening Lead- For every 1% additional tin, Brinell hardness increases 0.3. For every 1% additional antimony, Brinell hardness increases 0.9. For a simple equation, Brinell = 8.60 (Antimonial Lead) + ( 0.29 * Tin ) + ( 0.92 * Antimony )
lead, silver, and antimony, which reflects the composition of their felsic volcanic host rocks. They also have mound-like morphology and the abundance of coarse clastic sulfide minerals within many of these deposits attests to a moderately high energy, seafloor depositional setting. Kuroko-type deposits also tend to be underlain by copper-rich

Antimony hardens / strengthens lead. It helps the alloy flow and fill out the mould with better, sharper detail. It is extremely brittle and if the bullet is for other than paper punching the antimony should be held to about 6% of the alloy. Antimony is …
tinguish them from environmental sources of lead, barium, and antimony eliminates the threshold problem inherent in bulk elemental analysis. Although the amount of gunshot residue on the hand of a live s:ubject declines rapidly with time, this independence from a quantitative restriction makes detection
I bought a spring-loaded stainless steel mesh ball for making loose-leaf tea as well as a small stainless steel kitchen sieve. I bent the handle on the sieve to 90 degrees. I first put a piece of antimony in the stainless mesh ball and SUBMERGED it in the lead. I moved it around under the surface a while and it started to melt nicely.

Made from 90-percent lead, five-percent tin and five-percent antimony, Lyman No. 2 comes out to a Bhn of 15. Lyman No. 2 alloy is great for most non-magnum handguns and rifle loads with a velocity ...
If you have lead alloy that is too hard, you can also try melting it down and mix in what you know to be true, soft lead. It will still technically be an alloy, but you can "thin it out", so to speak, and make the ratio greater favor of lead over the antimony and tin. What Scrap Lead Can Be Used for Cap and Ball Revolvers

The Hardball Bullet Casting Alloy consists of 2% tin, 6% antimony and 92% lead. This modern version of the old Lyman #2 is an excellent all-around alloy for most handgun bullets and many higher velocity rifle cartridges. The Brinell Hardness of Hardball Alloy is about 16. Price listed is per pound and they are sold by the pound in 5 pound ...
The lead-antimony tailing and the rough zinc concentrate are merged, dispersant is added into the mixture, and the mixture is recovered through dispersing floatation, once crude dressing, thrice fine dressing, twice scavenging and returning middling to obtain qualified zinc concentrate while discarding final tailing.
Hornady took their popular Round Balls and made them tougher by using a lead alloy hardened with antimony to give the extra hardness and penetrating power needed for thick-skinned or large game. Hard Balls are created with the same exacting precision as …

Lead - Antimony alloys have high corrosion resistance in most enviroments. They form a protective, impermeable film even faster than pure lead and in some cases even faster than chemical lead. It is found that except in the presence of florine compunds, 6% antimonial lead is more resistant to corrosion than is soft lead. 6% Antimony, 92% Lead ...
The use of lead-antimony hardened balls will increase the efficiency of ball milling with the advantage of heavy milling balls, while at the same time reduce any lead contamination. Hardened lead does not dent or flake off, and will last longer than the mill itself.

The "Cartridge S.A. Ball .303 inch Cordite Mark III" was introduced in October 1897 to Design RL9762 and shown in LoC Paragraph 9762. It had a round nosed bullet with a cupro-nickel envelope and lead/antimony core. The nose had a hollow point, into which a cupro-nickel cup was inserted. The propellant charge was 31 grains of Cordite size 3 ...

Rather, the best way to get antimony into your alloy is to use other lead alloys, which are high in antimony (already dissolved.) Such additives include clip on wheel weights, linotype, and monotype. Clip on wheel weights contain about 3-4% antimony, and are (as air cooled) about 10-11 BHN.

Antimony: 2.06% Lead: 95.9% Hardness: 11.1 Bhn As mentioned above by the boys, you need that tin to help the lead to flow; it reduces the surface tension of the lead and allows it to fill out the cavity properly, otherwise you'll get bullets as wrinkly as my scrotum. If you go 1:1 eg 10 lbs Lyman to 10 lbs Pure, you'll get this: Tin: 2.5% ...
Trojan's grid technology is a lead antimony alloy grid mixture formulated specifically for use with Trojan's Alpha Plus Paste with T2 Technology. The grid formulation provides exceptional structural adhesion between the Alpha Plus Paste and the grid frame. Thick grids reinforce the strength of the frame and reduce overall corrosion.
