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 *5% of Russia's steel , *2 % ferrous metals , *0 % 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 ( *5%), magnesite (*5% ),
talc (*0%) , metallurgical dolomite ( *1%)
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 **0% 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) *******1 (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 *******1 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
*9,*9%. Using standard technologies it is almost impossible to
reach result higher than *9,**7%, in other words, the sum of
admixtures according to the standard list less than *0 ppm.
Individual results could be higher than *9,*9% , but guarantees not
less than *9,*9% or no more than **0ppm of admixtures.
Our company produce Oxygen Free Copper with purity level not less
than *9,******9,****9% according to the list of supervised
admixtures of GOST *******1 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 *9.*****9.*****9 % 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 *9.*****9.*****9% *
Shape according to specifications of the customer or ~ cylindrical
ingots**
Size according to specifications or ~ cylindrical ingots D*****0mm
x H*****0mm.
* Purity is defined by a difference between **0 % 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.
