Metal billets, metal slabs, and metal blooms are large, massive blocks or rounds that are produced from a primary metal or during a recycling process. They are used as raw materials or feedstock in extrusion, forging, rolling, and other metal-processing operations. Metal billets are round, rectangular, or hexagonal ingots or cast, semi-finished stock with a cross-section that is suitable for secondary processing. Billets are sometimes called bar stock, and are sold as cut-lengths or coil. Metal slabs are flat, semi-finished, rolled ingots with a specific width and cross-dimensional section. Metal blooms are large, square sections that represent an intermediate step in the rolling process.
