What are several options for procuring lead tin and antimony for casting

Industrially there are two casting procedures: the more classical one in which it can be converted into ingots ("ingot casting") or the "continuous casting" procedure. Ingot mould casting: This is the conventional tinplate steel casting process. By means of a ladle, the molten metal is poured into ingot moulds, which once cooled give.

Following is a listing of various types of lead and their approximate percentages of tin or antimony. Commercial Pig Lead - 99.6% lead; Cable Sheathing - 98.5% lead; Battery Lead - 90% lead and 10% antimony; Plumbers Solder - 67% lead and 33% tin; Wheel Weights - (varies) may contain anything from aluminum to zinc, in addition to antimony and lead; Type Metal - 82% lead, 15% antimony and 3% tin.

A good all-purpose alloy for both pistol and revolver bullets is 10 parts lead to one part each of tin and antimony. Depending on your source of lead, which might be scrap cable sheathing, lead pipe or odd scraps of lead of unknown alloy, you can make a good workable alloy by adding one part tin. An easy source of tin, by the way, is plumber's solder. Adding one part tin to wheel weights, which already contain antimony, makes good hard bullets.

Antimony. The largest applications for metallic antimony are an alloy with lead and tin and the lead antimony plates in lead–acid batteries. Alloys of lead and tin with antimony have improved properties for solders, bullets, and plain bearings. Antimony can be used in fire retardants for many commercial and domestic products.

Zinc is not a bullet alloy component. You are thinking of antimony, the main hardening addition to lead. Antimony is 6 to 10 times the price of lead. Tin is 10 to 20 times the price of lead. It's not cheap. Lead alloy ALWAYS costs more than soft lead. So, C&B balls are made of the cheapest possible lead alloy - dead soft lead.

  • Lead shot in bags is going to be dead soft lead, and not very useful in and of itself for 9mm. You'd need to add some tin, and ideally some antimony, to the mix to get an alloy hard enough for 9mm. I'd agree with selling the lead shot (which is more valuable than scrap lead anyway), and buying the scrap lead you need for bullet casting. 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. In machined or structural products, antimony adds rigidity to the design. Pure lead acts like butter on a warm day and the use of antimony will stiffen the alloy to allow machining to take place and keep the part.

Standard lead alloys for bullets are lead/ tin with up to 9% tin, lead antimony with up to 6% antimony and lead/tin/antimony mixes. Nuclead can also offer custom ammunition metal formulations. To control the hardness of shot used in shotgun shells, varying amounts of antimony are added to the lead shot, forming lead alloys. Radiation shielding.

Legend: Pb – lead Sn – tin Sb – antimony As – arsenic BHN – Brinell Hardness number Not even Lyman, one of the most foremost authorities on bullet casting, can agree. In the Lyman Reloading Handbook, 45 th Edition, wheel weight is stated to contain “about” ( ~ ) 9% antimony (Sb) which is “about” 5% more than the 3 rd Edition. But the addition of modest amounts of tin and antimony to the lead makes the metal considerably harder and better suited to both accurate casting and easier cleanup. A type of lead alloy referred to as "linotype" is a very good choice for bullet casting.
