About CEP Freiberg
CEP Freiberg develops and produces powder-metallurgical copper high-temperature materials (ODS copper) and offers them as semi-finished products and finished parts. The CEP DISCUP® brand materials combine high electrical and thermal conductivity with high strength and temperature resistance up to a recrystallization temperature of approx. 900 °C. Using the RMML process from ECKA Granules, used exclusively, a granulate is produced which is processed by indirect and hydrostatic extrusion as well as hot isostatic pressing (HIP) into round bars, profiles and double-wall composite tubes (pure copper outside, copper high-temperature material inside). From the CEP DISCUP®+Cu composite tube, the company manufactures current contact tips for MIG, MAG and UP welding systems and arc spraying, TIG patented clamping sleeves as well as wire guides for winding, turning and EDM machines. Customers include system manufacturers such as BINZEL, FRONIUS, DINSE, CLOOS and SKS. Founded in 2003 out of the Research Institute for Non-Ferrous Metals (FNE), the company produces in Freiberg/Saxony with great manufacturing depth and delivers directly from the factory.
