What is the best way to identify the quality of rectangular copper wire?

Certain key aspects can be examined carefully to determine rectangular copper wire quality. Assessing rectangular copper wire quality requires consideration of the following factors:

The rectangular copper wire's dimensions and geometry should be measured. Additionally, its length should be the same as its thickness, width, and height. Measure these dimensions and compare them with the specifications. Quality may be lower in different-sized wires.

Check the copper wire's surface for irregularities. Wires of high quality have a smooth, uniform surface without scratches, dents, burrs, or other visible defects. Check for roughness or irregularities on the wire.

Conductivity and purity are important for copper wire. Copper wire should be made from high-quality copper. Copper's composition and conductivity level are revealed by tests and certifications.

Make sure the wire is flexible and tensile. Copper wire should be able to withstand mechanical stress without breaking or deforming. Furthermore, it should be flexible enough to be bent or formed without cracking.

Copper offers excellent corrosion resistance. Check if the rectangular copper wire has been properly treated or coated to enhance its corrosion resistance. This is particularly important

The reputation and reliability of the manufacturer should be considered. High-quality copper wire is more likely to be produced by established manufacturers. Quality management system certifications, such as ISO 9001, indicate manufacturers' commitment to quality.

By carefully examining these factors, you can assess the quality of rectangular copper wire and make an informed decision based on your specific requirements and application needs.

The rectangular copper wire contains a high percentage of copper, 99.90%~99.97%, which is very difficult to identify with the naked eye. If we peel off a small piece of plastic sheath when purchasing the item, we will be able to see the copper wire inside. Use the palm of your hand to lightly touch the top of the copper wire. The copper core of a qualified copper core wire should be purple, shiny, and soft to the touch. Copper wire of regular wire is bright and reddish, while copper core of fake and inferior copper core wire is purple-black, yellowish or white, with numerous impurities, poor mechanical strength, and poor toughness. It is not uncommon for disconnections to occur. If you wish to check the copper core, simply peel off the wire by 2cm and rub a piece of white paper on it. White paper with black substance indicates that the copper core contains more impurities. There is a noticeable difference in color and hardness between the superior and inferior copper wires. Shape the copper wire into a small circle. When copper wire contains too many impurities, such as copper-clad steel wire, it will rebound. In the event that the copper is of higher quality, it will not rebound and form a circle. The copper wire should then be slowly straightened and restored. This indicates that the copper wire is made of high-quality material when it has been completely restored.rectangular copper wire,rectangular copper wire China,rectangular copper wire Manufacturer,rectangular copper wire supplier
