How to distinguish pure copper wire?
Pure copper wire is a high-performance wire material, which is widely used in power transmission, home appliance manufacturing, machinery manufacturing, chemical industry and other industries. However, due to the wide variety of copper materials, many counterfeit and inferior products have appeared on the market over time. As consumers, if we understand the corresponding identification methods, we can effectively avoid being defrauded. Here are some simple identification methods.
1. Appearance inspection method
Checking the color of the copper wire core is the simplest method. Pure copper is purple-red and has a good metallic luster, a smooth surface and strong reflective ability. Counterfeit or poor quality copper may have coatings or surface treatments of other colors, such as gold, silver, etc., which are very different from the color of pure copper.
2. Sound detection method
In addition to appearance inspection, we can also identify copper by listening to the sound of the copper core. Just tap the surface of the copper gently and listen carefully. If it makes a persistent sound and the sound disappears slowly, it is pure copper. Because the knocking sound of inferior copper is very sharp and disappears quickly.
3. Weight test method
We can take pure copper wires of the same length for comparison. Because the density of copper is smaller than many other materials, we can identify wires mixed with other materials by comparing the weight of wires of the same length.
4. Magnetic test method
Copper itself is not magnetic. If a wire is attracted to a magnet or sucked up, it means that the wire is doped with magnetic metals such as iron or nickel. If it cannot be attracted, it may be a pure copper wire.
In addition to the above methods to detect and identify whether it is pure copper, the most important thing is that when we purchase wire and cable products, we must choose manufacturers with good reputation and good credibility. Foshan Yuejiaxin Wire and Cable Co., Ltd. was established in 1999. It is a high-tech enterprise integrating R&D, production and sales of wires and cables. It is also a "specialized and new" enterprise in Foshan. At the same time, it has become one of the few companies in the cable industry that has obtained CNAS laboratory accreditation. With perfect quality testing, it ensures the reliability and safety of each product and can provide a safe, stable and long-term safe channel for power transmission in a variety of harsh environments.
