| 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. |
