Data sheet: Copper tubes for electrical applications

At Bronmetal we supply high quality round, square, rectangular and oval copper tubes for electrical applications. In the technical data sheet section you will find a wide variety of copper alloys and other metals so that you can choose the one that best suits your needs: Cu-ETP, Cu-FRHC, Cu-OF, CuAg0,10, CuAg0,10P, CuAg0,10(OF), Cu-PHC, Cu-HCP. Other alloys are available on request.

The mechanical characteristics and electrical properties are the same for all electrical copper tubes – regardless of their shape. However, tolerances will vary depending on their composition: tolerances on the outer diameter of round tubes, tolerances on the dimensions between faces of square and rectangular tubes and tolerances on wall thickness.

NOTE 1 - The IACS % values are calculated as percentages of the normalized value of high conductivity annealed copper, according to those established by the International Electrotechnical Commission. Copper whose volume resistivity is of 0,017 24 Ω x m, at 20ºC, is defined as that corresponding to a conductivity of 100%.
NOTE 2 - 1 MS/m is equivalent to 1 m/(Ω x mm²).
^a Calculated with a copper density of 8.89 g/cm³
^b IACS: International Annealed Copper Standard.
