Data sheet: Flat copper bar / rectangular bar

The copper strip is manufactured with quality materials according to the most relevant international standards. It can be used in connections, installations, capital goods or conduits related to the electrical sector, among others. We offer the option of tin plating, which increases protection against corrosion and improves the solderability of the product.

During the manufacturing process, the copper strip is tested for electrical properties at a temperature of 20°C to calculate the volume resistivity, mass resistivity and conductivity. In the electrical properties section you will find all the detailed information for each type of copper alloy.

The admissible current is in accordance with DIN 43671, which determines the currents of the copper bars at an ambient temperature of 35°C and a final temperature of the bars of 65°C. Depending on the width x thickness of the individual copper bars, the alternating current up to 60 Hz, the direct and alternating current 16 2/3 Hz and the static characteristics are calculated.

When you place your order, you can choose the form of supply that best suits your needs: flat, roll or rolled. In all options we offer you a wide variety of sizes – both in thickness and width – so that you can find the one that best suits your work. In addition, we also have a weight calculator that will help you determine the weight and measurements of the material to order.

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.
