Pure lead/tin casting alloy, specially mixed for us. 96% lead, 4% tin. One ingot fills a typical casting pot. $2.25 per pound.
A note about shipping: Lead is heavy, and our website calculates shipping costs based on weight. In some cases we can use flat rate boxes for lead, but unless we build a frame to put inside the USPS box, the flat rate boxes are not strong enough to survive a trip with 20 or more pounds of lead inside. If it is cost effective for you we will ship in a specially-reinforced flat rate box and you may get a partial refund on your shipping.
