6N, 7N high purity copper

6N, 7N high purity copper

It is high-purity copper at the world’s highest level of 6N (purity approximately 99.9999%).

We have started the import and sale of high-purity copper at the world’s highest level of 6N (purity approximately 99.9999%). The manufacturer is CHANGZHOU XINGLONG HI-NEW METAL PRODUCTS CO., LTD, located in Changzhou, China, which has established a production system for 6N (purity approximately 99.9999%) high-purity copper with an annual output of 120 tons, making it the first Chinese manufacturer to do so. Generally, the purity of electrical copper supplied for electric wires and drawn copper products is 4N (99.99%). "High-purity copper" refers to copper that has significantly increased in purity through re-refining, and it is used in wiring materials for semiconductor devices, ultra-high-end audio equipment, biological medicine, sputtering target materials, damascene anodes, bonding wires, and more. Particularly in recent times, the miniaturization of semiconductors has rapidly advanced, and the demand for high performance in devices has become increasingly stringent, leading to a growing need for high-quality high-purity copper with fewer impurities and smaller variations in the amounts of each impurity.

When comparing thermal conductivity by material, the cost-performance of copper becomes apparent.

When comparing thermal conductivity by material, the cost-performance of copper becomes apparent.

Introducing the important "thermal conductivity" for measuring the cost-performance ratio of metals, starting with copper!

There are several types of metals, but do you know which one offers the best cost-performance ratio? The answer (or rather, the author's opinion) is copper, which is commonly encountered, such as in 10-yen coins. Some of you might be thinking, "That makes sense," or perhaps you're curious about what aspects to focus on when evaluating the cost-performance of copper. Therefore, this time, we will introduce the important concept of "thermal conductivity" for measuring the cost-performance of metals, including copper, and we will also explain the thermal conductivity and market prices of various metals. *For more detailed information, you can view the related links. For more details, please download the PDF or feel free to contact us.*

Leave the pressing and cutting processing of metal foils such as copper and aluminum to Otis.

Leave the pressing and cutting processing of metal foils such as copper and aluminum to Otis.

We excel at processing thin metal foils that are difficult to work with, minimizing wrinkles and burrs, and enhancing added value through punching and laminating processes.

Metal foils are used in battery electrodes, capacitors, electromagnetic wave shields, and heat dissipation materials, among others. Their thickness is very thin, ranging from 1 μm to several tens of μm, making them materials that are prone to burrs and wrinkles during processing. At Otis, we select and analyze cutting tools to minimize defects such as burrs and wrinkles, even for thin metal foils that are difficult to process, allowing us to perform high-speed and high-precision punching operations. Additionally, we not only provide bubble-free laminates that protect surfaces from rust and corrosion, but we also combine them with different materials such as resin films to enhance added value through punching, bonding processes, and layering and compounding, which are our areas of expertise. At Otis, we manufacture processing equipment such as presses, molds, and jigs in-house. Through customization and development of our equipment, we have a proven track record of processing materials and shapes that other companies could not handle. Please feel free to consult with us.

[Column] Understanding Copper: Characteristics of Copper

[Column] Understanding Copper: Characteristics of Copper

Introducing the main features of copper, such as its excellent electrical conductivity, good thermal conductivity, and antibacterial properties!

Copper is the metal with the longest history, and its use dates back to 8000 BC. Copper has very superior properties compared to other metals. In recent years, especially, the trace metal action of copper (super antibacterial performance) has been attracting attention. This page introduces the main features of copper. Copper is the metal with the second highest electrical conductivity after silver, and it serves as the standard for the electrical conductivity of metal materials. Due to this property, it is widely used as an essential component in electronic devices. *For more details, please feel free to contact us.
