Description of material HOVADUR® CCNB:

HOVADUR® CCNB is a thermally precipitation hardenable copper alloy. In heat treated condition, the alloy combines high hardness and high resistance to heat with good electrical and thermal conductivity. The technological properties are improved by replacing part of the cobalt (see former DIN standard CuCo2Be; Material No. 2.1285) by nickel. We also produce the alloy HOVADUR® CCNBeh which is based on the same chemical composition as HOVADUR® CCNB. Its even higher quality is due to vacuum technology and special processes.

Application examples HOVADUR® CCNB:

  • Electrodes, holders and shafts for spot, seam, flash butt and projection welding of (preferably) material showing higher strength and electrical resistance (e. g. stainless and heat resistant steels) as well as welded wire mesh
  • Moulds for non ferrous metal casting
  • Inserts in steel moulds in areas requiring a higher cooling rate
  • Die casting pistons for horizontal cold-chamber die casting machines
  • Die venting for light metal die casting moulds
