| Brown Sharp Gages | (english) A standard series of sizes refered to by numbers, in which the diameter of wire or thickness of sheet metal is generally produced and which is used in the manufacture of brass, bronze, copper, copper-base alloys and aluminum. These gage numbers have a definite relationship to each other. In this system, the decimal thickness is reduced by 50% every six gage numbers- while temper is expressed by the number of B&S gage numbers as cold reduced in thickness from previous annealing. For each B&S gage number in thickness reduction, where is assigned a hardness value of 1/4 hard. |

| Buckles | (english) Appeaars like a series of waves and are created during rolling as a result of mechanical misalignment or cross-section irregularities in supply coil. |

| Bundle | (english) Specific number of sheets which equals 1 unit of production. Number is determined by multiplying sheets/Packages/BUNDLE. For example, an order calls for 112 sheets/package. According to the maximum height allowed for a lift. Therefore, multiplying 15 packages X 112 sheets 3D 1680 sheets/bundle. |
| Burning | (english) (1) Permanently damaging a metal or alloy by heating to cause either incipient melting or intergranular oxidation. (2) In grinding getting the work hot enough to cause discoloration or to change the microstructure by tempering or hardening. |
| BURST PRESSURE | (english) The level of pressure at which a component, pipe, tube, hose or other fluid passage will burst during application of internal pressure. Normally 2.5 - 4.0 times working pressure. |
| Busheling | (english) A widely traded form of steel scrap consisting of sheet clips and stampings from metal production. Bushel baskets were used to collect the material through World War II, giving rise to the term. |
