Copper powder

Copper powder is a stable isotope *3Cu and *5Cu with a purity of *9,**9%, which corresponds to technical condition TU ********************4. The sum of the impurities (Mg, Al, Ti, Fe, Al, Zn, Mo, Cd, Sb) is no more than 0,**1% of the total amount of **0%. The copper powder is superfine an average grain size of *5 micrometers. Based on the customer request the production and the supply of ultrafine copper powder are possible with a grain size from 1 to 7 micrometers. In this occasion the material purity is decreasing to *9,*9%. The specific natural radioactivity of the copper powder is no more than 1.*0^**1 Ci/g.
