Thousands factories must reconvert for peacetime production meet the greatest demand for goods the history our country. Obsolete worn out machinery must discarded and new equipment installed. Whenever necessary, methods must brought date and improved. Metal specifications must subjected the most searching examination determine whether the best possible material being used. Engineers and designers must bring themselves date finding out what new alloys have become available, what improvements have been made existing alloys and the engineering properties these modern alloys. Requirements are more severe, and the demand for materials capable taking more punishment. The war period has acted proving ground. Restrictions materials and labor necessitated the use machines and equipment beyond their rated capacities. Both design and materials either proved themselves fell the wayside. many cases new materials, some which may have been intended for substitute purposes, proved superior long-established metals and alloys. Today engineers are setting higher standards for both design and material specifications. Progress Copper-Base Alloys The non-rusting properties, workability and other fine characteristics copper- base alloys have been known for genera- tions. However, may not generally realized what extent copper-base alloys have been endowed with the engineering properties dependability, high strength, exceptional resistance wear and corro- sion, and high fatigue resistance. result this progress new horizons have been opened for brasses and bronzes and their usefulness greatly extended into wider fields. Wide Range Alloys Available longer must engineers designers choose rustable material simply because high strength required put with moderate strength because workability necessary. Through metallurgical research and advances processing methods and equipment, wide range engineering copper-base alloys available help manufacturers produce dependable, uni- form product price which will permit reasonable profits. Bridgeport has much offer not only from the standpoint modern engineering alloys such the Duronzes, cupro nickel and improved phosphor bronzes, but also complete line quality brass mill prod- ucts for the thousands applications which they can fill best. Bridgeport Brass Technical Handbook bring the design engineer, metal- lurgist, and purchasing agent date the various copper-base alloys that are available; their physical, chemical and mechanical properties; and the specifica- tions which apply them Bridgeport Brass Company has published 128-page technical handbook which soon released the trade. The technical handbook deals briefly with general information such the useful properties which have made copper-base alloys part and parcel modern civiliza- tion; the results current research and development and the new engineering alloys that are available. Also included the copper-zinc alloy system and the effect additional elements such lead, tin, aluminum, silicon, iron, nickel, arsenic, etc. the properties copper-base alloys. The effect annealing and cold working the microstructure and physical prop- erties brass discussed. The tempers rolled flat products and drawn tubing are explained detail and should very helpful understanding metal specifica- tions. The causes and prevention stress corrosion cracking and hot breaks are also included. Since lubricants have important bear- ing metal working, space devoted the various types and characteristics lubricants used for blanking, cupping, drawing, forming and machining. chap- ter metal cleaning discusses solvent cleaning, degreasing, alkaline scouring, emulsion scrubbing, electrolytic cleaning and tarnish removal. The most common acid cleaning formulae are also given. brief discussion drawing tools for sheet metal included. For simplification and easier understand- ing alloys have been grouped the basis their application. the strip and sheet section, for example, have nine alloys ranging from high brass oxygen-free copper, which are suitable for drawing, spinning and stamping. Each these alloys briefly described composi- tion, special characteristics and applica- tions. This followed table which shows seven these alloys side side. The table gives the complete analysis, mechanical properties such tensile strength, yield strength, elongation and Rockwell hardness; physical constants such melting point, density, coefficient thermal expansion, thermal and electrical conductivities and modulus elasticity. Under fabrication properties are given ma- chinability ratings, cold and hot working characteristics and hot working range. Also included are the specification numbers such ASTM, Federal, Navy, etc. which these materials belong. Other groups alloys under the strip and sheet section are engineering alloys for drawing, spinning and stamping, leaded brass strip, corrosion resisting tin brasses and spring metals. the rod and wire section the alloys are grouped under headings such rod and tubing for screw machine operation; rod and wire for cold heading, rods for hot forging and welding rod. Tables similar those under the strip and sheet section have been compiled with each group alloys. the section devoted tubing, the various methods for processing tubing are described and illustrated. The various al- loys have been grouped under headings such tubing for fabrication, condenser and heat exchanger tubing, duplex tubing, brass and copper pipe and copper water tubing. make this handbook still more useful numerous tables showing comparison wire gauges, fractions inch, temper- ature conversions and weights strip, circles, rod, wire and tubing and similar data have been included. Our object distribute this handbook widely among purchasing agents, engineers, designers, metallurgists and chemists, who are active the non-ferrous metal working field.

CREVICE CORROSION— PART the last two articles causes corrosion discussed the mechanism crevice corrosion and listed typical ex- amples. Crevice corrosion occurs those spaces formed particles resting metal surfaces, threaded connections, nails driven into wood, points contact, corners, mechanical joints, etc. shall now con- sider greater detail various procedures which have been used eliminate crevices prevent corrosive liquid from get- ting into the crevice. Some the problems connected with crevice corrosion have not yet been solved. hoped that this discussion will suggest means overcom- ing these difficulties. Prevention Crevice Corrosion brief description few methods which have been used overcome crevice corrosion filters and settling tanks are intended prevent foreign material from settling out metal surfaces. Plastic, rubber metal sleeves which are either permanent can periodically replaced will protect metal tie rods and bolts touching wood and passing through wood vinegar and pickling tanks. ness the use plastic metal sleeve critical areas cables, sheathes and piping resting moist duct walls and planking may materially lengthen the time before failure occurs. Heavy, viscous, tacky material such tar-like substances, have been used eliminate the crevice between metal roofing and wood. Also, changes design may prevent the retention water between the roofing contact with wood. Oil with without corrosion inhibi- tors widely used keep water out the interior wire rope, cable and stranded wire. Frequently, necessary resort the use more corrosion resistant materials. The most corrosion resistant material usually resorted order prevent keep minimum crevice corrosion wire gauze screen where the wires cross one another. Under some conditions, additional protection can obtained through the use paint lacquer. PRODUCTS SHEETS, ROLLS, STRIPS— Brass, bronze, copper, Duronze, for stamping, deep drawing, forming and spinning. CONDENSER, HEAT CHANGER, SUGAR TUBES— For steam surface condensers, heat exchangers, oil refineries, and process industries. BRIDGEPORT PHONO-ELECTRIC* High-strength bronze trolley, messen- ger wire and cable. WELDING ROD—For repairing cast iron and steel, fabricat- ing silicon bronze tanks. LEDRITE* ROD—For making automatic screw machine products. Heavier sections are installed locally such structures tanks and heat exchang- ers, order lengthen the life the structure. The elimination crevices through proper design great impor- tance. Welded, soldered filled joints aid preventing crevice corrosion between piping and fittings, nuts and bolts, etc. Welded, soldered filled joints have, many instances, replaced riveted joints. For many applications has been shown that the weld line corrodes rate greater than that the plates each side it. Improved Phosphor Bronze for Longer Lasting Spring Contacts such applications switches, radio and radar equipment, jack plugs, auto- matic controls and similar parts, more generous use the finest phosphor bronze available does not appreciably affect the cost the article, but increases its de- pendability and service life immeasurably. Volume control Mallory and Co., Inc. Contact arm made from Improved Phosphor Bronze. above volume control made Mallory and Company, Inc., who have this say concerning the re- quirements for the spring contact arm: “Long life, good current carrying characteristics, constant dependable spring pressure and flexibility plat- ing finishes.” Bridgeport’s improved phosphor bronze, when made into properly designed springs can withstand millions cycles flexing without failure. possesses high tensile and yield strengths well exceptional corrosion resistance. From the manufac- turers’ standpoint practical alloy because can readily formed into com- plex shapes. Other applications for Bridge- port’s improved spring phosphor bronze are diaphragms, bellows for radiator valves and steam traps, etc. Phosphor bronze also used for engineering applications such clutch discs and equipment paper mills and water works and sewerage plants.
