3. Main application / Special features of CW118C:
CW118C is used in particular in electronics and electrical engineering, e.g. for contacts, but also for welding torch nozzles, screws, nuts, parts for screw connections and valve parts. CUTeP is a suitable material if good machinability is required in addition to high electrical conductivity and increased softening temperature.
* The maximum available nominal size of each condition depends on the required shape.
