| DESCRIPTION OF THE
MATERIALS: |
| CuCo2Be Copper Alloy contains
approximately 2,5% Cobalt, 0,3% Nickel and 0,5% Beryllium. After hot
forging and heat treatment processes this
material gains considerably good hardness with good
electrical and thermal conductivity. Compared to
CuCoNiBe, CuCo2Be has slightly better mechanical and
physical properties. |
| APPLICATIONS : |
| Spot welding electrodes, electrode holders
and seam welding discs in resistance welding. Plunger tips
in Aluminium Die Casting machines. Injection
nozzles, cooling pins in plastic injection machines.
Moulds for casting of non-ferrous material. Chill moulds
in casting of brass and bronze material.
