Copper hot forging
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
Cu-ETP
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
Cu-Cr-Zr
Copper comprising 0.5 to 1.2 % of chromium
The heat treatment considerably increases its mechanical characteristics
