Corrosion of. power-station condenser tubes by polluted, waters has been particularly troubles ome in Japan anil efforts have been made to,study the problem by, electrochemical methods and by exposing model condensers at a variety of bower station sites ., Improved results have been reported, using tin. brasses , or special, tin bronzes. . Pretreatment with sodium dimethyldithiOcarbamate is reported to give protective films that will withstand the action of polluted waters , though the method would be economic only in special circurtistapcies., , , . ... 

Mixing molten copper with other metals yields a variety of alloys, such as bronze when alloyed with tin, brass with zinc, and arsenical copper with arsenic (see Table 34 and text below). All these alloys have extremely good mechanical and working properties and have, therefore, been employed for applications requiring strength and hardness (West 1982). 

Tin brasses Tin bronzes More resistant to SCC than Cu-Zn alloys Crack in NH3 and HgN03 when the alloys are cold worked SCC susceptibility increases with Sn content... 

Though water solutions, or aqueous solutions as they are known to the chemist, are probably the most familiar solutions, there are many other kinds of solutions. There are solid solutions such as metal alloys, although not all alloys form truly homogenous blends. Bronze is an alloy of copper and tin, brass is an alloy of copper and zinc, and steel is an alloy of iron and carbon. 

Rutamguiar SitM (lor nitrocellulose). A brass frame of internal dimensions 7 in. by si in. is coveted with tinned brass wire gause with 10 meshes per inch. 

Fibers and chips of nonferrous metals and alloys like copper, brass, aluminum, zinc, and bronze are used in friction materials to provide the desired friction and wear performance. Porous and solid metal powders like tin, brass, copper, bronze, and iron are also used in some products. As mentioned earlier, some metal powders are also used as binders in sintered formulations. 

DCP (120-83-2) Combustible solid (flash point 237°F/114°C). Dust forms explosive mixture with air. Reacts violently with strong oxidizers, acids. Incompatible with caustics. Quickly corrodes aluminum slowly corrodes zinc, tin, brass, bronze, copper, and its alloys. Flow or agitation of substance may generate electrostatic chtirges due to low conductivity. 

Reactions with metals. In the absence of water, quicklime does not react with metals. However, see section 19.2 for the reaction of hydrated lime with the amphoteric metals (namely aluminium, lead, tin, brass and zinc). Iron and steel are not attacked and are widely used as materials of eonstruction in lime handling plants. 

Brasses Alloys that have zinc as a major alloying element this group contains the copper-zinc alloys, the copper-zinc-4ead alloys (leaded brass), and the copper-zinc-tin alloys (tin brasses)...
