Copper plate

Product details:

Application:

Copper plate has many unique properties, so it is widely used. In the electronics industry, it is a key material for printed circuit boards, and its good conductivity ensures stable signal transmission. In terms of architectural decoration, it can be used for exterior wall decoration, roof cladding, etc. The patina formed by the oxidation of the copper plate gives the building a simple and unique beauty, and it has good weather resistance and can maintain its appearance for a long time. In the field of artistic creation, copper plate is easy to carve and etch, and artists use it to create exquisite copper prints, sculptures and other works, showing rich artistic expression. At the same time, in the manufacture of heat exchangers, copper plate can transfer heat efficiently due to its high thermal conductivity, improve heat exchange efficiency, and play an important role in chemical, HVAC and other industries.

  Product Features:

1. Excellent electrical conductivity

Copper plate is a copper plate with extremely high copper content. The conductivity of copper is second only to silver, and the electrical conductivity of copper plate can usually reach a very high level, about 58-62×10⁶S/m. This makes it widely used in the electrical field, such as for making wires, cables, busbars, motor windings, etc. In electronic equipment, copper plate can effectively conduct current and reduce the loss of electric energy during transmission.

2. Good thermal conductivity

Copper plate has excellent thermal conductivity, and its thermal conductivity coefficient is as high as 385-401W/(m·K). This feature makes it an ideal material for heat exchangers, radiators and other heat dissipation equipment. For example, in the radiator of a computer CPU, the copper plate can quickly conduct the heat generated by the CPU, dissipate the heat into the air through the heat sink and fan, and ensure that the CPU works within a suitable temperature range.

3. Excellent ductility and plasticity

Copper plate has good ductility and is easy to cold and hot process. During cold processing, it can be rolled and stretched into products of various shapes and thicknesses. For example, copper sheets can be rolled into very thin copper foils for use in electronic shielding or packaging. In terms of hot processing, such as forging and extrusion, copper sheets can also be well formed, making it convenient to manufacture complex copper products.

4. High chemical stability

Under normal conditions, copper sheets are chemically stable. It is not easy to react with oxygen, moisture, and many common chemicals in the air. However, in a humid environment containing carbon dioxide, the surface of the copper sheet may slowly oxidize to form patina (basic copper carbonate), but this patina can also protect the inside of the copper sheet to a certain extent.

5. Beautiful appearance and surface characteristics

Beautiful color: The copper sheet presents a unique purple-red color, which is highly recognizable and decorative. In the fields of architectural decoration, artistic creation, etc., the color of the copper sheet can add a simple and elegant temperament to the work. Good surface quality: After processing, the surface of the copper sheet can achieve a high degree of finish, which can reflect light and enhance the visual effect. And through surface treatment methods such as polishing and brushing, the copper plate can present different textures to meet diverse aesthetic needs.

6. High recyclability

The copper plate is a recyclable material. The recycling value of copper is high, and the recycled copper plate can be reprocessed into new copper products through smelting and other processes. This not only saves resources, but also reduces production costs, which is in line with the concept of environmental protection and sustainable development.
