| Bright Annealing 2 | (english) The process of annealing in a protective atmosphere so as to prevent discoloration of the bright surface desired. |
| Bright Dipping | (english) Chemical polishing of aluminum, often by treatment with a mixture of nitric acid and phosphoric acid, yielding a mirror-shiny (specular) highly reflective surface. It is almost always followed by anodizing to protect the surface and provide some choice of color. |
| Brine | (english) A saltwater solution for quenching or cooling when heat treating steel. |
| Brinell Hardness Test | (english) A common standard method of measuring the hardness of materials. The smooth surface of the metal is subjected to indentation by a hardened steel ball under pressure. The diameter of the indentation, in the material surface, is then measured by a microscope and the hardness value is read from a chart or determined by a prescribed formula. |
| Brinell Hardness Testing | (english) Method of determining the hardness of materials; involves impressing a hardened ball of specified diameter into the material surface at a known pressure (10-mm ball, 500-kg load for aluminum alloys). The Brinell hardness number results from calculations involving the load and the spherical area of the ball impression. Direct-reading testing are generally used for routine inspection of forgings, and as a heat treat control function. |
| Brite | (english) 1) Regular galvanize coating (not minimized spangle or JP). 2) Rolls that have no grit; smooth finish on surface of steel. |
| Brittle Inter-metallic Layer | (english) An iron-zinc alloy layer formed between the steel substrate and the free zinc of galvanized coatings. |
| Broaching 2 | (english) Multiple shaving, accomplished by pushing a tool with stepped cutting edges along the piece, particularly through holes. |
| Bronze | (english) An alloy containing 90% copper and 10% tin. Used for screws, wire, hardware, wear plates, bushings and springs; it is somewhat stronger than copper and brass and has equal or better ductility. |
| Bronze 2 | (english) Primarily an alloy of copper and tin, but additionally, the name is used when referring to other alloys not containing tin, for example, aluminum bronze, manganese bronze, and beryllium bronze. |
