Due to the manufacturing process, discs are not free of traces of processing. Follow-up treatment of the surface may be necessary!
Copper ETP is an oxygen-containing copper with a high conductivity (400 W / (m * K)) for heat and electricity. It can also be formed extremely well. The strength in the recrystallized state is <200 N / mm².
Due to the residual oxygen content, which can lead to hydrogen embrittlement, the material is not suitable for welding. However, the solderability is excellent.
Components for electrical engineering, electronics and architectural applications are manufactured from copper ETP with the EN designation CW004A.
