We can customize it.99.9% oxygen-free copper productionOxygen free copper price = ordinary copper * 1.5 times = copper clad aluminum price * 2-3 timesWhy is oxygen-free copper so good? Pure copper that is oxygen free and does not contain any deoxidizer residue. The appearance of copper oxide in the form of inclusions at the grain boundaries has a negative effect on the toughness of the material. While the oxygen in the oxygen-free copper is very low, the uniformity of the copper structure is advantageous for the toughness of the single-phase structure.Polyester enameled wire:The polyacetate enameled wire has a heat rating of 130, and the modified enameled wire has a thermal rating of 155. The product has high mechanical strength, good elasticity, scratch resistance, adhesion, electrical properties and solvent resistance. It is the largest production in China, accounting for about two-thirds: widely used in various motors. Electrical appliances, meters, telecommunications equipment and home appliances.1. In the case of the same number of turns and volume, the "inductance" value of the hollow inductor is much lower than the solid inductor;Hollow inductors are more suitable for high frequency applications, while solid inductance has a serious frequency tendency;That is to say, the hollow inductive reactance allows most of the audio or audio to pass, and the solid inductive reactance is selective, allowing only a portion to pass.2. The reason for using these two types of inductive reactance is because of the need for audio and/or audio;In the frequency divider, the hollo
