Copper

Copper is characterised in particular by its high electrical and thermal conductivity and is therefore an important material for applications in electrical engineering and e-mobility. At the same time, suitable copper materials offer good properties for cold forming.

MN Kaltformteile processes various copper materials for cold forming, including Cu-ETP1, Cu-ETP, Cu-OF1 and Cu-OF.

Copper for electrical engineering and e-mobility

Copper is used in particular where high electrical or thermal conductivity needs to be combined with precise component geometry. This makes the material particularly attractive for applications in electrical engineering and e-mobility.

MN Kaltformteile also manufactures cold-formed copper components for high-voltage systems in e-mobility. These include, for example, copper threaded bolts for inverters, as well as copper sleeves and contact elements for high-voltage systems.

Cold forming enables high material utilisation, as the component geometry is largely created through forming rather than material removal. Particularly with a valuable material such as copper, this can make a significant contribution to material-efficient series production.

In addition to copper, MN Kaltformteile also processes copper alloys such as brass, as well as other copper-based materials.

“We talk a lot about electrification and the energy transition. However, both can only work with the right material. Copper is a good example of this: known for millennia and more important today than ever before. With a valuable raw material in particular, it is crucial to use the material as efficiently as possible. Cold extrusion combines high material utilisation with the cost-effective production of precision components.”

Copper: Questions and answers

Why is copper used for technical components?

Copper has high electrical and thermal conductivity and is therefore suitable for numerous technical applications. The material is particularly relevant, for example, for electrical connections and contact elements in electrical engineering and e-mobility
Can copper be cold-formed?

Yes. Suitable copper materials can be processed by cold forming or cold extrusion. This allows complex component geometries to be produced with high material utilisation. Which grade of copper is suitable depends, amongst other things, on the component geometry, the degree of forming and the required material properties.
Which copper materials does MN Kaltform use?

MN Kaltform processes, amongst others, Cu-ETP1, Cu-ETP, Cu-OF1 and Cu-OF. The selection of the appropriate copper material depends on the technical requirements of the component and the forming process.
Where are cold-extruded copper components used?

Cold-extruded copper components are used in fields such as electrical engineering and e-mobility. MN Kaltformteile manufactures, for example, copper threaded bolts for inverters, as well as copper sleeves and contact elements for high-voltage systems.
What advantages does copper offer in e-mobility applications?

Copper’s high electrical conductivity makes it particularly attractive for transmitting high currents, as well as for electrical connections and contact elements. At the same time, its high thermal conductivity offers advantages in applications where heat needs to be dissipated in a targeted manner. MN Kaltformteile manufactures cold-formed copper components, for example, for high-voltage systems and inverters.
