High-purity Oxygen-free Copper (ofc) Has A Wide Range Of Applications And Many Chinese Manufacturers
Jun 27, 2024
High-purity oxygen-free copper (OFC) refers to high-purity copper alloys with extremely low oxygen content and no other impurity elements. High-purity oxygen-free copper has the advantages of good thermal conductivity, good electrical conductivity, corrosion resistance, good welding performance, and high purity. It is suitable for power systems, semiconductors, precision electronic instruments, audio equipment and other fields with extremely high requirements for electrical conductivity.
The core raw material of high-purity oxygen-free copper is high-purity copper ingot. Copper is a bulk commodity, and its production and sales have maintained a long-term growth trend. According to data released by the National Bureau of Statistics, my country's copper production will reach 22.17 million tons in 2023, a year-on-year increase of 4.9%. Yunnan, Tibet, Inner Mongolia, Jiangxi, Xinjiang and other places are the main copper production areas in my country. At present, my country's copper mines are mainly associated ores, and there are problems such as high impurity content in the ore and difficulty in purification, resulting in a low output of high-purity copper ingots, which will bring certain challenges to the development of the high-purity oxygen-free copper industry.
The preparation methods of high-purity oxygen-free copper include industrial frequency induction furnace smelting method and vacuum furnace smelting method. The industrial frequency induction furnace smelting method refers to placing the copper material into a preheated industrial frequency induction furnace and smelting to obtain the finished product. This method has the advantages of good finished product quality and high finished product yield, and is suitable for large-scale production; the vacuum furnace smelting method is suitable for the preparation of ultra-high purity oxygen-free copper, which has problems such as low finished product yield and high operating cost, and is widely used in overseas companies.
According to the "2024-2029 China High-purity Oxygen-free Copper (OFC) Industry Market In-depth Research and Development Prospects Forecast Report" released by the Xinshijie Industry Research Center, high-purity oxygen-free copper has excellent conductivity and is widely used in power systems, semiconductors, precision electronic instruments, audio equipment and other fields. In the field of power systems, high-purity oxygen-free copper can be used to manufacture cable wires; in the field of semiconductors, it can be used to manufacture printed circuit boards and electronic components; in the field of audio equipment, it can be used to manufacture speaker signal transmission lines. In the future, with the increasing demand for applications, the development space of my country's high-purity oxygen-free copper industry will be further expanded.
There are many high-purity oxygen-free copper production enterprises in my country, mainly including Guangdong Olai High-tech Materials Co., Ltd., Shaanxi Sirui New Materials Co., Ltd., Zhejiang Libo Industrial Co., Ltd., Tongling Nonferrous Metals Group Co., Ltd., etc. Olai New Materials focuses on the research and development, production and sales of high-performance sputtering targets and related products, and is actively promoting the construction of a high-purity oxygen-free copper production base project, with a project construction period of 2.5 years.
Industry analysts
said that high-purity oxygen-free copper, as a high-performance copper material, is widely used in many fields with extremely high requirements for electrical conductivity.
