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 also fitting parts. CUTeP is a suitable material when good machinability is required in addition to high electrical conductivity and an increased softening temperature.
* The respective maximum available nominal dimension of each state depends on the required shape.
