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
