Characteristics of hot-forged copper

  • Hot forging allows important deformations, refines the starting grain, create a favorable linear drawing
  • Hot-forged brass offers the advantage of excellent material health, good surface condition, no porosity
  • Numerous coating like silvering, tinning
  • Copper offers an ideal conductivity for all the electrical applications
  • It allows easy assemblies by stirring or crimping
  • Recycling copper is easy and economical, environmentally friendly
  • hot forged copper offers better mecanical characteristics than high pressure die casting


Different copper famillies


Pure electrolytic copper (99.9%)

Used for electrical applications


Cu-Te P 

Copper comprising 0.4 to 0.7% of Tellurium

Good machinability, used for electrical applications



Copper comprising 0.5 to 1.2 % of chromium


The heat treatment considerably increases its mechanical characteristics
