For other uses, see Billet (disambiguation).

Billet is a term used in manufacturing to refer to a cast product. A cast product is defined as either as ingot or a billet, depending on whether the cross-sectional diameter is greater than, or less than approximately 200 mm, respectively. A billet is typically cast to a geometry compatible with secondary processing, e.g. forging. An ingot is typically cast to a convenient geometry for further primary processing, e.g. heat treatment (Schey, 1999). Ingots and billets are collectively known as barstock.
