The Hendrix Group - aluminum bronze - oil & chemical industries Aluminium bronze (CA102 or UNS 60800) tubes are sometimes used with tubeplates of CA105 or CA106 in heat exchangers especially when these are operating under relatively high pressure and it is desired to weld the tubes to the tubeplates. Aluminium bronzes are, however, also used for small items in a very wide variety of chemical environments where high resistance to corrosion and erosion are required. Aeration increases the rate of corrosion of aluminium bronzes in sulphuric acid and greater acceleration is caused by the presence of oxidising agents such as ferric salts, dichromates or nitric acid. www.hghouston.com /coppers/bronze42.htm   (1764 words)

The Hendrix Group - Corrosion of Aluminum Bronze Nickel aluminium bronze requires more care in welding to avoid formation of cracks in either the weld or the parent metal but, since it is not subject to stress corrosion in sea water, no subsequent stress relieving treatment is required. Nickel aluminium bronze, manganese bronze and high tensile brass are all used for cast underwater fittings such as propeller shaft brackets and rudders and in conditions of free exposure to sea water are satisfactory. Aluminium bronze is not generally used in small stopvalves for domestic water installations except for valves that are to be installed underground. www.hghouston.com /coppers/bronze41.htm   (2422 words)

Aluminium bronze - Wikipedia, the free encyclopedia Aluminium bronze is a type of bronze in which aluminium is the main alloying metal added to copper. Aluminium bronzes are most valued for their higher strength and corrosion resistance as compared to other bronze alloys. Aluminium bronzes' resistance to corrosion rests in the aluminium component of the alloys, which reacts with atmospheric oxygen to form a thin, tough surface layer of alumina (aluminium oxide) which acts as a barrier to corrosion of the copper-rich alloy. en.wikipedia.org /wiki/Aluminium_bronze   (407 words)

Bronze Information Presented on bronze   (Site not responding. Last check: 2007-10-13) Bronze and bronzes with focus on the bronze statues bronze sculptures and statues. Bronze was still used to a considerable extent during the Iron Age, but for many purposes the weaker iron was sufficiently strong to serve in its place. Bronze is still widely used today for springs, bearings, bushings and similar roles, and is particularly common in the bearings on small electric motors. www.importliquidators.com /bronze_q.html   (1068 words)

Aluminium Powdered aluminium and rust in the approximate ratio of 1:3 are packed in a refractory crucible with a magnesium ribbon, or a powder of magnesium and barium peroxide, to ignite it. Aluminium can be protected by a thick layer of oxide made by electrolysis, a process called "anodizing." The surface is first thoroughly cleaned and degreased in trichloroethylene, or by electrolysis, where the aluminium is the cathode and the grease driven off by the evolved hydrogen. Aluminium sulphate is found in nature as the rare mineral Kalinite, which is soluble in water, so it is found only near volcanoes and such places where it is make by the action of sulphuric acid on clays, such as on Lipari, near Vesuvius, and a few places in Germany and South America. www.du.edu /~jcalvert/phys/alumin.htm   (4695 words)

Bronze uses and properties Contemporary bronzes are typically copper alloys that may contain silicon, manganese, aluminium, lead, iron and other elements, with or without tin. Aluminium bronze is a copper-aluminium alloy that may contain iron, nickel, and/or silicon for greater strength.

aluminium bronze valves   (Site not responding. Last check: 2007-10-13) Aluminium bronzes are copper-base alloys with around 5% to 11% aluminium. Aluminium bronze valves are particularly resistant to corrosion by sea water where they are most frequently used. Aluminium bronzes also have good resistance to sulphuric acid, sulphur dioxide and other combustion products and also show low rates of oxidation at high temperatures. www.aluminium-bronze-valves.com /index.html   (164 words)

Fraser 101 - Bronze, what is it Bronze, like brass, is a manufactured product and was one of the first alloys developed by ancient metal workers. Aluminium bronze is used to make tools and, because it will not spark when struck, many things that will be used around flammable materials. Aluminium bronze is also used for aircraft and automobile engine parts. www.awfraser.co.nz /bronze_101.htm   (689 words)

Bronze - Wikipedia, the free encyclopedia Bronze, commonly known by the symbol Bz, refers to a broad range of Copper alloys, usually with tin as the main additive, but sometimes with other elements such as phosphorus, Manganese, Aluminium, or silicon. Bronze was stronger than the era's iron; quality steels were not widely available until thousands of years later, although were produced in late celtic oppida and in China. Bronze parts are tough and typically used for bearings, clips, electrical connectors and springs. en.wikipedia.org /wiki/Bronze   (971 words)

Smiths Metal Centres - Bronze Stockholder - Bronze Supplier Bronze is the oldest alloy known to man. It is an alloy of copper and tin but it is more often used with other alloying elements included.

Smiths Metal Centres - Aluminium Stockholder - Aluminium Supplier Aluminium, in its usable form, is a relatively new metal that is produced using an electrolytic process. In its pure form, the metal is easily worked and possesses a high level of corrosion resistance, but its low strength reduces the number of applications for which it is suitable. There are two main types of alloyed aluminium; wrought and cast. www.smithmetal.com /products/Aluminium.htm   (449 words)

Outokumpu - Aluminium bronze The addition of aluminium to copper gives a range of alloys with properties that give exceptional performance in many critical areas of plant and component engineering. Aluminium bronzes couple excellent tensile strength with good ductility, and retain these properties from cryogenic temperatures up to at least 300 degrees C, even under fluctuating or impact loads. Aluminium bronzes are well suited to conditions where direct contact with water or steam is necessary, and will withstand many aggressive conditions. www.outokumpu.com /pages/Page____9976.aspx   (266 words)

aluminium the name aluminium was adopted to conform with the "ium" ending of most elements, and this spelling is now in use elsewhere in the world. Aluminium was also the accepted spelling in the U.S. until 1925, at which time the American Chemical Society officially decided to use the name aluminum thereafter in their publications. The method of obtaining aluminum metal by the electrolysis of alumina dissolved in cryolite was discovered in 1886 by Hall in the U.S. and at about the same time by Heroult in France. www.speclab.com /elements/aluminum.htm   (1770 words)

Sculpture Community - Sculpture.net - Thermal aluminium bronze patination... Pretty much all the color in bronze patina comes from copper salts, (sometimes modified with iron salts) Aluminum, zinc and tin salts are all color less and as a rule of thumb will lighten the patina. As far as the copper and iron salts which color bronze, they do have a different atomic or molecular arrangement from the alloy and won’t bind as tightly, but in cases like this, particle size matters greatly. ISIS, unfortunately--because she lives on the truck's campertop,-- is out on the roads being bathed by acid polution and salty water sprayed up from wet road surfaces, so I have to repair and recoat her every 2-3 years. www.sculpture.net /community/showthread.php?t=673   (3118 words)
