World Metal Source Headquarters
Company Information
WORLD METAL SOURCE has been founded by Saoud bin Faisal Al-Qassimi and a group of international businessmen with strong background as well in production as in marketing. World Metal Source is a company based in Abu Dhabi, United Arab Emirates, with strong roots in Russia and Western Europe.We have own productions in Belarus, Kazakstan
Ukraine, Chelyabinsk, Novosibirsk Russia and work directly with
the biggest mines in metall industry in Russia.
are world market leaders.
We can offer highly competetitive prices and fast deliveries.
Chelyabinsk is one of the major leading industrial centers in Russia. Heavy industry predominates, especially metallurgy.
(about 25% of Russia's steel , 22 % ferrous metals , 20 % of steel pipes ) and colour (melting zinc, etc. ) metallurgy, engineering and metalworking ( low power electric motors , radio receivers , tractors , refrigerators and freezers , trucks, mining and metallurgical equipment , heavy ATVs , tools,) ;
chemicals ( fertilizers , synthetic resins, varnishes and paints ); military industry , mining (brown coal , ferrous and non-ferrous metals , magnesite) . Chelyabinsk region is a monopolist in the Russian mining and processing of graphite ( 95%), magnesite (95% ), talc (70%) , metallurgical dolomite ( 71%)
SPESIAL PURITY COPPER and SPECIAL PURITY OXYGEN-FREE COPPER
Copper of special purity used in microelectronics, the chemical industry, machine building, the atomic industry, the defense industry 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 a difference between 100% and the sum of supervised admixtures
Supervised admixtures - the list of elements, measured into a sample, in order to define the level of purity.
Wider the list of supervised admixtures - lower the level of purity, expressed in percentage of content of core element. Herewith, the purity of product is constant, but the result defined in 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 the methods can equally and deeply measure controlled admixtures.
For instance, with just one method its possible to measure a group of elements with limit
Variety of standards can define supervised admixtures. The most common standard in Russia is GOST (ГОСТ) 859-2001 (All Union State Federal Standard). Europe and many other countries normally use technical condition sign Cu-OFE or others. Also, supervised admixtures can be agreed between consumer and manufacturer. Usually parties define not only the list of supervised admixtures, but the ultimate content of some of these admixtures.
GOST 859-2001 and technical condition sign Cu-OFE describe requirements for purified oxygen free copper. According to this list of supervised admixtures guarantees the level of copper purity 99,99%. Using standard technologies it is almost impossible to reach result higher than 99,997%, in other words, the sum of admixtures according to the standard list less than 30 ppm. Individual results could be higher than 99,99% , but guarantees not less than 99,99% or no more than 100ppm of admixtures.
Our company produce Oxygen Free Copper with purity level not less than 99,9985-99,99999% according to the list of supervised admixtures of GOST 859-2001 and Cu-OFE standard
Our company has knowledge and practical experience in manufacturing materials of the high purity for semi-conductor and other areas. In particular, we have experience in manufacture of copper of special purity 99.999-99.999999 % depending on specifications.
Copper of special purity is applied in microelectronics, the chemical industry, machine building, the atomic industry, the defense industry and in other areas.
We can manufacture and offer you and/or your partners SPESIAL PURITY COPPER and SPECIAL PURITY OXYGEN-FREE COPPER in ingots:
Purity 99.999-99.999999% *
Shape according to specifications of the customer or ~ cylindrical ingots**
Size according to specifications or ~ cylindrical ingots D50-100mm x H50-200mm.
* Purity is defined by a difference between 100 % and the sum of agreed controlled impurities
** ~ cylindrical ingots are the truncated cone similar to the cylindrical shape.
That is necessary for us to know:
The list of impurities for the control, maximum content of impurities, 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 on demanded specifications (purity, the form and the size) necessary volumes, at what time and price.
