Manufacturing Process & Heat Treatment of Copper Round Bar
Annealing
Annealing of copper round bars involves heating the material to a temperature range of 600°C to 800°C, followed by controlled cooling. This process relieves internal stresses, enhances ductility, and improves the overall mechanical properties of the copper, making it easier to work with in subsequent manufacturing processes.
Forging
Forging is a critical manufacturing step where copper round bars are shaped under high pressure. The process typically occurs at elevated temperatures (around 700°C to 900°C), allowing the copper to deform plastically. This results in improved grain structure and mechanical strength, ensuring the final product meets stringent quality standards.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 950 - 1050 | Water | To increase hardness and strength of the copper |
| Tempering | 300 - 500 | Air | To reduce brittleness and improve toughness |
| Stress Relieving | 200 - 300 | Air | To relieve internal stresses after machining |
The combination of these manufacturing processes and heat treatments ensures that the copper round bars produced meet the high standards required for global export, offering exceptional strength, ductility, and resistance to wear.
