HOVADUR® CNBspez is a thermally precipitation hardenable copper alloy. In hardened condition, the material is characterized by high electrical and thermal conductivity combined with very good hardness and resistance to heat. HOVADUR® CNBspez is especially suitable for applications requiring high electrical (and / or thermal) conductivity combined with great hardness. Due to vacuum technology and special processes, clearly better properties compared to standard quality HOVADUR® CNB can be garanteed.
Application examples HOVADUR® CNBspez:
Electrodes, holders and shafts for spot, seam, flash butt and projection welding of (preferably) material showing higher strength (e. g. stainless and heat resistant steels) and welded wire mesh.
Moulds for non-ferrous metal casting, especially appropriate for low pressure die casting
Inserts in steel moulds in areas requiring a higher cooling rate
Continuous casting moulds for steel casting
Thermally high-strained parts susceptible to fire cracks
