Code : DIN 17666 – W. Nr. 2.1293 – 44759, A2/2, EN: CW 106C, AFNOR: UC1Zr, USA: CDA: C18150, C18200, C18400, RWMA: Class 2, CuCr1Zr
 

Cupro Max CuCrZr Material Properties: This is a copper alloy with high electrical conductivity. When alloyed with chromium and zirconium, wear resistance increases. Wires can be shaped by erosion.

Cupro Max CuCrZr Areas of Application:
•Electrode tips and disks of low carbon steel and galvanized steel in resistance welding
• Continuous casting steel and aluminum moulds
• Plunge spark erosion machine electrodes
• Refrigerator parts and moulds for casting of non-ferrous metals
• The pistons of aluminum injection molding machine
• Plastic packaging welding and seam welding ends
• Nozzles of injection molding machines
• As cathode plate carrier and in electroplating
• Plastic extrusion and forming tool used in refrigeration
• In electrical equipment, contacts, pins, contact bars
