oxygen free copper wire production line

In today’s pursuit of sustainable development, the use of waste copper wire to produce oxygen-free copper wire (OFC) has become a model of resource recycling. Oxygen-free copper is widely used in high-end electronics, audio equipment and special cables due to its excellent conductivity and extremely low oxygen content (≤0.001%). This recycling process not only realizes the recycling of resources, but also creates significant economic value.

The recycling process of waste copper wire begins with fine sorting and processing. Through advanced mechanical crushing and sorting technology, high-purity copper materials can be extracted from waste cables and electronic waste. Subsequently, these copper materials undergo processes such as vacuum melting and electrolytic refining to remove impurities and ensure that the copper purity reaches more than 99.99%. The smelted copper liquid is formed into copper rods through continuous casting and rolling, and then through multiple drawing and annealing under nitrogen protection, it is finally made into oxygen-free copper wire that meets the requirements. After surface treatment and packaging, the finished product can be put on the market. This process is not only efficient, but also can maximize the retention of the excellent properties of copper.

From an economic perspective, recycled oxygen-free copper wire from scrap copper wire has significant cost advantages. The price of scrap copper is usually 20%-30% lower than that of electrolytic copper, while the price of recycled oxygen-free copper wire is close to that of primary copper products, which makes the profit margin reach 25%-40%. In addition, with the global emphasis on the circular economy, many countries and regions have provided tax exemptions and policy subsidies for scrap copper recycling companies, further enhancing the profitability of this industry.

Looking ahead, the recycled oxygen-free copper wire industry from scrap copper wire will usher in a broader space for development. On the one hand, the advancement of green technologies, such as hydrogen smelting and low-carbon processes, will drive the industry in a more environmentally friendly direction; on the other hand, the application of artificial intelligence and spectral technology will greatly improve the efficiency and accuracy of scrap copper sorting. At the same time, the demand for high-purity copper in emerging industries such as 5G communications and new energy vehicles continues to grow, providing a stable market support for recycled oxygen-free copper wire. Through technological innovation and refined operations, this industry will not only achieve environmental protection goals, but also gain long-term economic returns and become an important part of the circular economy.
