Oxidation Control
Protective atmosphere reduces surface oxidation and discoloration during annealing.
Copper Bright Annealing
Copper Bright Annealing Furnace
Protective atmosphere annealing solution for copper strip and copper foil processing, built to reduce oxidation, protect surface brightness and maintain stable conductivity.
copper bright annealing high surface quality stable conductivity oxidation control
Application
For copper processors that need a clean bright surface after heat treatment.
Copper bright annealing depends on atmosphere purity, temperature uniformity and exit cooling. AKS designs these systems together so copper strip and foil can leave the line with a stable finish and predictable electrical performance.
Bright Surface
Stable furnace temperature and clean atmosphere support high surface quality.
Conductivity Stability
Repeatable annealing curve helps maintain electrical properties by batch.
Technical Parameters
| Material | Copper strip, copper foil, brass strip and selected copper alloys |
|---|---|
| Annealing type | Continuous copper bright annealing under protective atmosphere |
| Atmosphere goal | Reduce oxygen exposure and protect copper surface brightness |
| Heating goal | Uniform thermal profile matched to copper thickness and target hardness |
| Cooling goal | Stable exit temperature to reduce surface color variation and deformation |
| Controls | Automatic control, alarms, process records and optional energy monitoring |
Atmosphere System
Atmosphere, heat and cooling must work as one process.
- Protective atmosphere control helps keep copper strip and foil bright.
- Temperature uniformity reduces batch-to-batch conductivity variation.
- Exit cooling control limits discoloration and shape instability.
- Process data supports quality tracking for continuous production.
