We simplify your small quantity procurement with our large CoppAl Bars from stock.
Do you want to save on stock management for large quantities and only order the production portion you need?
With our CoppAl semifinished product range of standard bars, you can also order individual busbars or small quantities from buzzbar. Our CoppAl bar procurement is spread across several suppliers due to the risk of failure. We have tested and approved our dealer structure.
All semifinished products have a standard length of 4000 mm and are provided for you on special wooden racks. We at buzzbar® will take care of the commissioning and delivery immediately after receiving your order.
Semifinished products are used as raw material for the production of busbars or other products. The procurement of smaller quantities is usually not possible.
The solution: Order CoppAl bars from the buzzbar® standard product range and get only what you really need! A standard length of 4000 mm allows you to be flexible in your further processing. Shorter CoppAl Bars can be found in our saw cuts.
Our CoppAl® Bars are a composite material made of copper and aluminum, also called CuAL or Cuponal.
The copper sheath encloses the aluminum core of the bars and, thanks to the hydrostatic pressing process, is inseparably connected to it. In this way, we can optimally combine the positive properties of highly conductive copper with the low weight of aluminum. CoppAl bars are cheaper with the same current-carrying capacity, and thus a cost-saving alternative to copper bars.
Simply process CoppAl® in the same way as you are used to with conventional copper bars. Even bends of more than 90° are no problem. Neither the copper sheath nor the aluminium core will be damaged with a bending mandrel.
No. Under normal conditions, such as those found in electrical operating rooms, no increased corrosion occurs.
Outside of electrical operating rooms, with increased humidity and the presence of electrolytes (e.g. sea air), you must expect increased corrosion at the cut edges and in the area of the holes. In case of doubt, we therefore recommend additional corrosion protection (e.g. galvanic finishing, paint coating, grease, acid-free Vaseline).
Yes. Galvanised screws or stainless steel screws can be used under normal conditions without any problems.
In most cases, the same holder spacing can be used as for copper bars.
Most commercially available holders can be used here. If you decide to use CoppAl® , however, you should note that an approximately 20 % larger cross-section must be used compared to copper bars for the same rated current.
The thermal behaviour is similar to that of copper rails. The dynamic properties are between copper and aluminum bars.
For CoppAl bars, DIN 43 670, Part 2 (copper-clad busbars made of aluminum) applies.
The standard bar length is 4000 mm. Other dimensions are available as saw cuts on request!
For CoppAl bars, the current-carrying capacity applies according to DIN 43670 – Part 2, copper-clad bars made of aluminum.
* Current load values: Ambient temperature 35 °C, AC current AC.
Heating of the busbar depending on: Current intensity, ambient temperature, heat dissipation, type of routing, installation, application Multiplication factor 1.72 when using 2 busbars, multiplication factor 2.25 when using 3 busbars in parallel arrangement.
After a successful request, you will receive your offer within one business day by e-mail.
