| DESCRIPTION OF THE
MATERIAL: |
| CuCr
contains approximately 1% Chromium possesing high conductivity and
better mechanical properties than unalloyed
copper with fairly good conductivity. After forging and heat
treatment it is possible to have better hardness and
mechanical properties. |
| APPLICATIONS: |
| Resistance welding electrodes, electrode
holders and seam welding discs. Current carrying arms, cable
connecters, electrical and thermal conducters
working under mechanical stresses. |
