About Us

•   GS Prominvest Ltd. is a young Bulgariancommercial company, which would like to expand on the world marketof non-radioactive metals with a super purity, metal alloys andstable isotopes. The company is an official trade house of themanufacturer company RedMetProm999 Ltd., Russsia. GS ProminvestLtd. has all the necessary permissions, authorizations and licensesto export and distribute non-radioactive metals with a superpurity, metal alloys and stable isotopes. The company hasrepresentative offices in Russia, Bulgaria, the Baltic countriesand USA.   GS Prominvest Ltd. offers you on its exclusive rightthe purchase of non-radioactive metals with a super purity, metalalloys and stable isotopes. Some of the products are:   Copper powder - it is a stableisotope Cu63 and Cu65 with a purity of 99,999%, which correspondsto technical conditions TU 793-011-50316079-2004. The sum of theimpurities (Mg, Al, Ti, Fe, Ni, Zn, Mo, Cd, Sb) is no more than0,001% of the total amount of 100%. The copper powder is superfine- an average grain size of 25 micrometers. Based on the customerrequest the production and the supply of ultrafine copper powderare possible with a grain size from 1 to 7 micrometers. In thisoccasion the material purity is decreasing to 99,99%. The specificnatural radioactivity of the copper powder is no more than 1.10-11Ci/g.   Copper ingots - the material purityis 99,999%. The sum of the impurities (Mg, Al, Ti, Fe, Ni, Zn, Mo,Cd, Sb) is no more than 0,001% of the total amount of 100%. Thespecific natural radioactivity of the copper ingots is no more than1.10-11 Ci/g.   Other isotopes: 112Sn      - purity > 99,0% 115SnO2 - purity > 65,0% 33S          - purity > 99,0% 184W       - purity > 95,0% 54Cr         - purity > 93,0% 112Te       - purity > 99,0% 204Pb       - purity > 99,0% 66Zn         - purity > 99,0% 187Os       - purity > 99,2%    Othermetals and alloys: Ni wire Al powder Zn powder In, purity 99,9% ÷ 99,99999% AuW alloy (Au - 83,25%, W - 16,35%)    Materials onstock: 63Cu and 65Cu, purity 99,995% - 22 000 kg 184W, purity 99,99% - 10 kg 187Os, purity 99,9% - 5 kg Ni wire, diameter 0,025 mm, purity 99,95% - 120 kg (27 272 760 m)    The productsmanufactored by RedMetProm999 Ltd. are supported by all thenecessary quality and quantity certificates: Certification, test report and quality and quantity certificate issued by IACC Giredmet Manufacturer quality certificate Production certificate of conformity according to requirements of radiological safety of RBP Certificate issued by IGAS (Independent Global Assaying Services)    The manufacturercompany RedMetProm999 Ltd. is able to produce non-radioactivemetals with a super purity, metal alloys and stable isotopes on acustomer request!
