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 this is by far the most popular with target shooters.
In lead-based alloys, antimony is added in the range of 1/2 percent to 12 percent and most commonly it is used in a range of 1/2 percent to 6 percent antimony and the balance of the alloy is lead or tin. The use of a little antimony in castings will help material flow so it acts to improve the feed into a part compared to pure lead.
Shot Hardness. We come now to the hallowed ground of shot hardness. The Sporting Arms and Ammunition Manufacturers Institute (SAAMI) tells us that “lead shot pellet hardness is established by the amount of antimony alloyed with the lead in the pellets and is varied by the manufacturer depending on the purpose for which the shotshell is designed.”
The antimony lead alloys that we supply to the clients are assured to be high quality. The Persentage of the Antimony can also be like 1% to 10 %. It is depends on the customer or the buyer that what composition he required.
Jan 09, 2019 In the past, lead was added with tin but the lead would often leach out of the finished pewter product when exposed to acids, making it hazardous when made into utensils. Today, lead-free pewter made with antimony or bismuth is desired when
Antimonial Lead. Antimonial lead is produced by adding Antimony to Lead. Antimony, number 51 on the Periodic Table of Elements, is a harder metal than lead, thus when mixed with lead, makes it harder and/or firmer. The percentage of Antimony depends upon your application or specifications. Antimonial lead can be supplied in multiple forms.
Nov 01, 2013 The reason that antimony is used in premium pellets is that it is expensive. In the past number of years antimony has fluctuated between $2 and $8 per pound. Lead is right around $1 per pound. That means that antimony is 2 to 8 times the cost of lead. The less antimony you can get away with, the less your shot will cost to make.
Antimony contents of lead-antimony alloys can range from 0.5 to 25%, but they are usually 2 to 5%. Lead-calcium alloys have replaced lead-antimony alloys in a number of applications, in particular, storage battery grids and casting applications. These alloys contain 0.03 to 0.15% Ca.
Currently, Gold Medal shot seems to be at or near the 6% level. As a generality, 6% antimony shot is only found in #7-1/2 and #8 target loads. Fiocchi says, "All Exacta line shells are loaded with 5% antimony lead, as opposed to the 3.2% antimony content used in Fiocchi's more economical Shooting Dynamics line of competition shells."
In the past, lead was added with tin but the lead would often leach out of the finished pewter product when exposed to acids, making it hazardous when made into utensils. Today, lead-free pewter made with antimony or bismuth is desired when made into dishes, decorative pieces and drinking vessels.

the alloy in terms of strength, handling, and improved production casting.1 Antimony is an element added to lead primarily to maintain the rigidity and structural integrity of the casted lead grids, thus improving the quality and yields during the battery manufacturing process. The concentrations of antimony to lead were initially in the 8% ...

Antimony, tin, arsenic, and calcium are the most common alloying elements. Antimony generally is used to give greater hardness and strength, as in storage battery grids, sheet, pipe, and castings. Antimony contents of lead-antimony alloys can range from 0.5 to 25%, but they are usually 2 to 5%.

Basically, what sets the standard is the resistence to deformation with 6% antimony in #9, #8, and #7 1/2 lead shot sizes. The percentage of antimony gets less as you go to bigger shot sizes, and the labeling is really one of equivilents. In other words, 4% antimony gives the same result (resistence to deformation) in #6 size shot as does 6% ...
Dec 21, 2016 For every 1% additional antimony, Brinell hardness increases 0.9. For a simple equation, Brinell = 8.60 + ( 0.29 * Tin ) + ( 0.92 * Antimony ) When you know the percentages of Lead, Tin and Antimony in an alloy you can easily and accurately determine the as cast and air cooled BHN hardness of the alloy by the formula.

Oct 20, 2020 Lead (Pb) and antimony (Sb) associated with bullets pose a long term contamination risk in shooting ranges because bullet fragments weather over years to decades. In this study we analyzed bullet and soil samples from a historic military shooting range in interior Alaska.

Feb 12, 2013 The 5% tin and 5% antimony with 90% lead in Lyman #2 has been the most popular hunting alloy for cast bullet shooters for well over 100 years because it has a very optimized mix of hardness and ductility for bullets that only need 1,000 foot pounds impact on game animals for double caliber expansion and 100% weight retention of bullets as they ...
A toxic heavy metal is any relatively dense metal or metalloid that is noted for its potential toxicity, especially in environmental contexts. The term has particular application to cadmium, mercury and lead, all of which appear in the World Health Organization's list of 10 chemicals of major public concern. Other examples include manganese, chromium, cobalt, nickel, copper, zinc, silver ...

May 28, 2013 In comparison to other toxic chemicals and metals like lead, arsenic, barium, and aluminum, antimony doesn't get as many mentions. However, it should. Because antimony is widely used and present in so many everyday items, the health concerns caused by exposure to toxic antimony compounds are a real threat.
