Copper profiles executed according to technical drawing
Copper profiles are semi-finished products obtained by hot pressing and cold drawing, having:
- a) Cu-ETP – high electrical and thermal conductivity and excellent plastic deformation properties. For this type of copper special precautions are required while heat treating, welding or soldering in a hydrogen atmosphere to prevent hydrogen embrittlement.
- b) Cu-DHP – has excellent welding, bonding and plastic deformation properties in both hot and cold conditions.
COMMON AREAS OF USE OF COPPER PROFILES BY DRAWING:
- for the construction of electrical and mechanical equipment,
- various components for the transport of electric current,
- in construction,
- art and architecture,
- design or decorative elements.
