Oxygen free copper wire refers to the conductor of the wire is no oxygen and does not contain any deoxidizer residues of pure copper. Although it is pure copper, it actually contains very small amounts of oxygen and some impurities. According to the standard, the content of oxygen is not more than 0.003%, the total content of impurities is not more than 0.05%, and the purity of copper is greater than 99.95%, which is pure copper, that is, oxygen-free copper.

The chemical composition of the conductor material of the oxygen-free pure copper wire is shown in the following table

Oxygen-free pure copper wire, of course, refers to the use of oxygen-free copper material as a wire, composed of one or several soft wires, and the outer bread is a light soft protective layer. Oxygen free pure copper wire is a carrier for conducting electrical energy use. The function of oxygen-free pure copper wire is to "conduct current". The conductor of the oxygen-free copper wire is oxygen-free copper, which has high purity, excellent electrical conductivity, thermal conductivity, cold and hot processing performance and good welding performance.

How to identify whether to buy oxygen free pure copper wire?

Anaerobic pure copper wire identification method 1: look at the anaerobic pure copper wire packaging, the national standard anaerobic pure copper wire is often better, neat, hand up with a sense of quality.

Identification method 2 of oxygen-free pure copper wire: To open the package to see the oxygen-free pure copper wire inside, the national standard of oxygen-free pure copper wire 1.5- 6 square wire requirements are skin thickness (insulation thickness) is 0.7mm, too thick is non-standard, the corresponding his inner core is certainly not enough, you can pull the wire skin, not easy to tear is generally the national standard.

Identification method 3 of oxygen-free pure copper wire: burn it, extinguish it within 5s after leaving, and have a certain flame retardant function for the national standard line.

The identification method of oxygen-free pure copper wire four: look at the inner core, the inner core material (copper) the higher the brightness, the better the copper, and the brightness is uniform, shiny, and there is no layer. The national standard requires that the inner core must be oxygen-free copper. Non-standard such as black rod copper, there may be a potential accident.

The identification method of oxygen-free pure copper wire five: the thickness of the inner core has certain requirements, but it is not very strict. But not a lot of mistakes, just a very small, generally with the eye can not see the error.

Anaerobic pure copper wire identification method six: length, the state does not force must hit the meter, but there are many manufacturers also hit the meter, hit the meter is not necessarily the national standard, but the general national standard generally did not hit the meter. Off-target shooting is just a means.

The identification method of oxygen-free pure copper wire seven: The state stipulates that the wire must be marked with a certain mark, which will not exceed 500mm and will have the next same mark, which generally has the product's trademark, the manufacturer's name, the implementation standard, etc.

Qingdao Tianxing Cable Co., Ltd. focuses on the production of customized wire and cable manufacturers, main: fire wire and cable, power cable, control cable and other products, exported to more than 40 countries and regions around the world, the annual production capacity of 1 billion yuan. 6000 square meters of storage, standing hundreds of millions of inventory, order demand for rapid distribution and delivery, large prices more favorable.
