| 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. |
