An open single-cavity bullet mold and a closed two-cavity mold. A cast bullet is made by allowing molten metal to solidify in a mold.Most cast bullets are made of lead alloyed with tin and antimony; but zinc alloys have been used when lead is scarce, and may be used again in response to concerns about lead toxicity.
A slab is a length of metal that is rectangular in cross-section. The slab is created directly by continuous casting or indirectly by rolling an ingot on a slabbing mill. [1] Slabs are usually further processed via flat rolling, skelping, and pipe rolling. Common final products include sheet metal, plates, strip metal, pipes, and tubes. [3]
An ingot is a piece of relatively pure material, usually metal, that is cast into a shape suitable for further processing. [1] In steelmaking, it is the first step among semi-finished casting products. Ingots usually require a second procedure of shaping, such as cold/hot working, cutting, or milling to produce a useful final product.
Today, approximately 96% of steel is continuously cast, while only 4% is produced as ingots. [16] The ingots are then heated in a soaking pit and hot rolled into slabs, billets, or blooms. Slabs are hot or cold rolled into sheet metal or plates. Billets are hot or cold rolled into bars, rods, and wire.

Components of a modern bottleneck rifle cartridge. Top-to-bottom: Copper-jacketed bullet, smokeless powder granules, rimless brass case, Boxer primer.. Handloading, or reloading, is the practice of making firearm cartridges by manually assembling the individual components (metallic/polymer case, primer, propellant and projectile), rather than purchasing mass-assembled, factory-loaded ...
Cast iron occurs when the iron absorbs 2% to 4% carbon. Because the bloomery is self- fluxing , the addition of limestone is not required to form a slag. The small particles of iron produced in this way fall to the bottom of the furnace, where they combine with molten slag, often consisting of fayalite , a compound of silicon , oxygen , and ...
