What are the characteristics and applications of copper strips What is the method of identification

Red copper is a kind of copper material. Because of its high copper content, it is also called pure copper in the industry, and it is more widely used in the electrical industry. Copper strip is one of the most common display forms of copper in the market. The general specifications are thickness: 0.1-3.0mm, width: 30-1000mm. Many friends do not have a deep understanding of copper strips.let me  introduce to you the characteristics and applications of copper strips, and what is the identification method of copper strip materials.

The Characteristics and application of copper strip theAccording to the different copper content, the copper strip is divided into three materials: T1, T2, and T3. Among them, the copper content is more than 99.95% as T1; the copper content is more than 99.90% as T2; the copper content is more than 99.7%. T3. The specific features and application scenarios are as follows:

1. The Characteristics and application of T1 copper strip the T1 copper strip has good electrical conductivity, thermal conductivity, corrosion resistance and processability, and can usually be welded and brazed. It contains fewer impurities that reduce electrical conductivity and thermal conductivity, and is mostly suitable for electrical, thermal and corrosion-resistant equipment such as electric wires, conductive screws, cables, chemical evaporators, storage devices, and various pipelines.

2. The Characteristics and application of T2 copper strip the The electrical conductivity, thermal conductivity, corrosion resistance and processability of the T2 copper strip are relatively good, and it has good weldability, and can be welded and brazed. Contains less impurities that reduce electrical and thermal conductivity. The electrical and thermal conductivity of copper is second only to silver, so it is widely used in the production of electrical and thermal equipment, chemical industry, etc.

3. The Characteristics and application of T3 copper strip the T3 copper tape contains relatively more impurities that reduce electrical conductivity and thermal conductivity, and the oxygen content is higher than that of T2. Trace impurities in T3 copper strip have a great influence on the electrical and thermal conductivity of copper, so it is mainly used as a structural material.

4. How to identify the material of the copper strip the The more intuitive way to distinguish T1, T2, and T3 copper strips is to test the composition content of the copper strip or test its conductivity. Under normal circumstances, in terms of conductivity, T1>T2>T3, the conductivity of T1 copper strip is above 65%, the conductivity of T2 copper strip is above 56%, and the conductivity of T3 copper strip is only about 36%.
