| DESCRIPTION
OF THE MATERIAL: |
| CuCoNiBe
Copper Alloy contains approximately 1% Cobalt, 1% Nickel and 0,5%
Beryllium. After hot forging and heat treatment processes this material
gains considerably good hardness, electrical and thermal conductivity.
It is possible to have different combinations of electrical conductivity
and hardness by changing the heat treatment conditions. |
| APPLICATIONS: |
| Spot
welding electrodes, electrode holders and seam welding discs in resistance
welding. Plunger tips in Aluminium Die Casting machines. Injection
nozzle, cooling pins in plastic injection machines. Moulds for casting
of non-ferrous material. Chill moulds in casting of brass and bronze
material. Due to its good surface quality, homogen and fast cooling
rate this alloy has an excelent working performance. |
