| Brass | (english) An alloy that is 70% copper,30% zinc. One of the most widely used of the copper-zinc alloys; malleable and ductile; excellent cold-working but poor hot-working and machining properties; excellent for soft-soldering; good for silver alloy brazing or oxyacetylene welding, but fair for resistance or carbon-arc welding. Used for drawn cartridges, tubes, eyelets machine items and snap fasteners. |
| Brasses | (english) Copper base alloys in which zinc is the principal alloying element. Brass is harder and mechanically stronger than either of its alloying elements copper or zinc. It is formable and ductile; develops high tensile strength with cold-working and is not heat treatable. |
| Braze Welding | (english) A family of welding procedures where metals are joined by filler metal that has a melting temperature below the solidus of the parent metal, but above 840 (450 C). |
| Brazing | (english) Joining metals by fusion of nonferrous alloys that have melting points above 800 F (425C), but lower than those of the metals being joined. May be accomplished by a torch. Filler metal is ordinarily in rod form in torch brazing; whereas in furnace and dip brazing the work material is first assembled and the filler metal may then be applied as wire, washers, clips, bands, or may be bonded, as in brazing sheet. |
| Breakout | (english) An accident caused by the failure of the walls of the hearth of the furnace resulting in liquid iron or slag (or both) flowing uncontrolled out of the blast furnace. |
| Bridling | (english) The cold working of dead soft annealed strip metal immediately prior to a forming, bending, or drawing operation. A process designed to prevent the formulation of Luder's lines. Caution-Bridled metal should be used promptly and not permitted to (of itself) return to its pre-bridled condition. |
| Bright Annealed Wire | (english) Steel wire bright drawn and annealed in controlled non-oxidizing atmosphere so that surface oxidation is reduced to a minimum and the surface remains relatively bright. |
| Bright Annealing | (english) A process carried out usually in a controlled furnace atmosphere, so surface does not oxidize, remaining bright. |
| Bright Basic Wire | (english) Bright steel wire, slightly softer than Bright Bessemer Wire. Used for round head wood screws, bolts and rivets, electric welded chain, etc. |
| Bright Bessemer Wire | (english) Stiff bright wire of hard temper. Normally wire is drawn down to size without annealing. |
