INDUSTRIAL COPPER SHEETS

Industrial copper sheets

Industrial copper sheets are semi-finished products obtained by cold rolling, having:

a) Cu-ETP - high electrical and thermal conductivity and excellent plastic deformation properties. For this type of copper special precautions are required when heat treating, welding or soldering in a hydrogen atmosphere to prevent hydrogen embrittlement.
b) Cu-DHP - has excellent welding, bonding and plastic deformation properties both hot and cold, but no emphasis on electrical and thermal conductivity.
