Silver alloyed copper wire rod

Катанка легированная серебром.jpg

Standards:

Silver alloyed copper wire rod is produced by JSC “Uralelektromed” in compliance with TU 24.44.23230001944292020 and BS EN 1977.

Application:

It is used in materials with high heat resistance requirements (higher than copper) without reducing electrical conductivity (production of railway contact wires, electric motor parts, semiconductor components and heat radiators).

Properties:

Silver alloyed copper wire rod of CuAg0.04, CuAg0.07 and CuAg0.1 grades is produced in compliance with TU 24.44.23230001944292020 and BS EN 1977.

The addition of silver to copper wire rod increases its creep resistance and softening temperature.

Nominal diameter of copper wire rod: 8 mm, 10 mm

Tolerance: ±0,3 mm

Note: Content of Cu and Ag combined is determined by subtracting the sum of impurities from 100%:

- the sum of mass fractions of elements (excl. Ag) obtained during the analysis conducted under a certain methodology is calculated with the accuracy specified in the methodology according to the table presented. If the content of the impurity-element in the sample is less than the lower limit of the element’s identification level provided in the methodology, then the content of this element shall be defined as the value of the lower limit of identification, and this value shall be used when calculating the content of the main component;

- the sum of impurities is then subtracted from 100%.
