How to choose flexible copper strands Soft copper stranded wire has a great difference in the quality of soft copper stranded wire due to the copper content and the equipment process of each production processing plant. Today, soft copper stranded wire manufacturers will teach you a few tricks to distinguish between good and bad soft copper stranded wire. Methods.

The so-called flexible copper stranded wire refers to a new type of composite wire which is made of high-carbon steel as the core, processed by copper plating, and several single wires are twisted according to the law. Soft copper stranded wire is a kind of soft connecting line for transmission and distribution, electrical devices (such as transformers, electric furnaces), electronic and electrical equipment, and thyristor components. In addition, soft copper strands can also be used for electrical work grounding. The soft copper stranded wire is realized by the equal-speed rotation of the stranded single-wire winding bobbin and the uniform forward movement of the stranded wire. Soft copper strands can be divided into hard and soft copper strands and soft copper strands. They each have their own characteristics and uses.

The toughness of a good flexible copper strand is very good. Take out a wire and bend it a few times. If it is easily broken, it means that the quality of this thin wire is not very good. There is also a thin plastic outer skin on the surface of the soft copper stranded wire. The high-quality soft copper strands will not ignite on the surface after ignition.

The parameters of copper-magnesium alloy density, specific heat capacity and thermal conductivity are not fixed, depending on the ratio of copper to magnesium, copper density is 8.9 g/cm3, magnesium density is 1.8 g/cm3, and if it is proportioned, it is considered to be melted into alloy. The atomic spacing becomes smaller, so the alloy density should be slightly higher than (8.9+1.8)/2 = 5.35; you can calculate the density of the alloy according to the volume ratio or mass ratio of the two metals in the conventional copper-magnesium alloy. The value will be close to the real value, but it will be slightly higher than the actual value; the specific heat and other parameters have to be tested to get.

Magnesium has high specific strength, high specific stiffness, good thermal conductivity and electrical conductivity, and has good electromagnetic shielding, damping, vibration damping, cutting processability and processing cost, processing energy is 70% of aluminum alloy and easy to recycle.
