WORLD METAL SOURCE has been founded by Saoud bin Faisal Al-Qassimiand a group of international businessmen with strong background aswell in production as in marketing. World Metal Source is a companybased in Abu Dhabi, United Arab Emirates, with strong roots inRussia and Western Europe.We have own productions in Belarus, KazakstanUkraine, Chelyabinsk, Novosibirsk Russia and work directly withthe biggest mines in metall industry in Russia. are world market leaders.We can offer highly competetitive prices and fastdeliveries. Chelyabinsk is one of the major leading industrial centers inRussia. Heavy industry predominates, especiallymetallurgy. (about 25% of Russia's steel , 22 % ferrous metals , 20 % of steelpipes ) and colour (melting zinc, etc. ) metallurgy, engineeringand metalworking ( low power electric motors , radio receivers ,tractors , refrigerators and freezers , trucks, mining andmetallurgical equipment , heavy ATVs , tools,) ;chemicals ( fertilizers , synthetic resins, varnishes and paints );military industry , mining (brown coal , ferrous and non-ferrousmetals , magnesite) . Chelyabinsk region is a monopolist in theRussian mining and processing of graphite ( 95%), magnesite (95% ),talc (70%) , metallurgical dolomite ( 71%) SPESIAL PURITY COPPER and SPECIAL PURITY OXYGEN-FREE COPPERCopper of special purity used in microelectronics, the chemicalindustry, machine building, the atomic industry, the defenseindustry and in other areas.One define the level of purity by content of core element. Also,purity of copper denominates by percentage and can be defined as adifference between 100% and the sum of supervised admixturesSupervised admixtures - the list of elements, measured into asample, in order to define the level of purity.Wider the list of supervised admixtures - lower the level ofpurity, expressed in percentage of content of core element.Herewith, the purity of product is constant, but the result definedin percentage of content of core element changes.Methods of analysis also plays a role on the level of purity -expressed in percentage of content of core element. Not all of themethods can equally and deeply measure controlled admixtures.For instance, with just one method its possible to measure a groupof elements with limitVariety of standards can define supervised admixtures. The mostcommon standard in Russia is GOST (ГОСТ) 859-2001 (All Union StateFederal Standard). Europe and many other countries normally usetechnical condition sign Cu-OFE or others. Also, supervisedadmixtures can be agreed between consumer and manufacturer. Usuallyparties define not only the list of supervised admixtures, but theultimate content of some of these admixtures.GOST 859-2001 and technical condition sign Cu-OFE describerequirements for purified oxygen free copper. According to thislist of supervised admixtures guarantees the level of copper purity99,99%. Using standard technologies it is almost impossible toreach result higher than 99,997%, in other words, the sum ofadmixtures according to the standard list less than 30 ppm.Individual results could be higher than 99,99% , but guarantees notless than 99,99% or no more than 100ppm of admixtures.Our company produce Oxygen Free Copper with purity level not lessthan 99,9985-99,99999% according to the list of supervisedadmixtures of GOST 859-2001 and Cu-OFE standardOur company has knowledge and practical experience in manufacturingmaterials of the high purity for semi-conductor and other areas. Inparticular, we have experience in manufacture of copper of specialpurity 99.999-99.999999 % depending on specifications. Copper of special purity is applied in microelectronics, thechemical industry, machine building, the atomic industry, thedefense industry and in other areas.We can manufacture and offer you and/or your partners SPESIALPURITY COPPER and SPECIAL PURITY OXYGEN-FREE COPPER in ingots:Purity 99.999-99.999999% * Shape according to specifications of the customer or ~ cylindricalingots** Size according to specifications or ~ cylindrical ingots D50-100mmx H50-200mm. * Purity is defined by a difference between 100 % and the sum ofagreed controlled impurities ** ~ cylindrical ingots are the truncated cone similar to thecylindrical shape.That is necessary for us to know:The list of impurities for the control, maximum content ofimpurities, required purity.The shape and the sizes of ingots.Necessary volumes, single or constant need.Having this information, we shall answer, whether we can make ondemanded specifications (purity, the form and the size) necessaryvolumes, at what time and price.
