Luvata strip and hollow conductor for emobility_1920x316
We're using our unique metals know-how to overcome the challenges facing the e-mobility industry. 

Thanks to our systematic development work, we have succeeded in developing a high-adhesion PA-12 coated copper strip. This product is ideal for the growing EV market and especially for battery connections.

We offer this product in a very soft temper, so it is easy to form and bend.  The product can be bent into sharp angular shapes and even loops, mean while the adhesion of the insulation remains tight. 

We typically deliver the product on reels, from which the customer can easily manufacture the components without unnecessary set-up times.

PA12 Coated Strip

  • Material Cu-OF
  • Excellent adhesion
  • Soft temper, R200
  • Flammability tested according to UL 94 HB
  • Supplied with reels
  • Dimensional range: width 8-20mm / thickness 2-6mm, full round edges
Electric vehicles (stator direct cooling)

Our hollow conductors provide new possibilities to cool down electric motors. The internal cooling hole on the stator windings enables efficient thermal transfer out from the core - exactly from the source where the heat is generated. Cooling with air improves the performance significantly and liquid cooling even more. As a result increased power and torque are achieved by direct cooling with Luvata's hollow conductors.

All impurities reduce the electrical conductivity of copper, which is why we make Luvata hollow conductors from OF-OK® high purity oxygen-free copper. As a result of its purity, Luvata OF-OK has typical electrical conductivity of 100-102 %IACS and thermal conductivity of 390 W/Km.

The maximum oxygen content of 5 ppm (0.0005%) makes the material immune to hydrogen embrittlement and ensures safe joining with all brazing and welding methods.

The OF-OK used in our hollow conductors is cast in our own  foundry in electric furnaces using selected high purity raw materials. This means we can control the whole manufacturing process from casting to signing the inspection certification, and ensure the consistency of our product from batch to batch.

When necessary OF-OK is alloyed with silver (Ag) to increase both the softening temperature and creep resistance of the alloy without any significant sacrifice of its other properties.
