Our copper clad aluminum sheet is a kind of sheet that combines copper and aluminum through hot-melt rolling technology, which is mainly used in power equipment and decoration.
The production process of copper clad aluminum sheet
Using pure aluminum or aluminum alloy as the base layer, the continuous casting semi-molten rolling composite method is used to composite copper and copper alloy strips with a certain thickness on one or both sides, and the composite interface is metallurgical bonding.

T2/1100 | Single clad | H18,H24 | 0.5-12 | ≤1000 | 10-30 |
T2/3003 | Single clad | H18 | 0.5-12 | ≤1000 | 10-30 |
T2/8011 | Single clad | O | 0.5-12 | ≤1000 | 10-30 |
Cladding copper metal
Copper or copper alloys that play various functional roles in copper clad aluminum sheet, usually T2 copper.
base aluminum
The aluminum or aluminum alloy for auxiliary rental in the copper clad aluminum sheet is usually 1060 aluminum or 3003 aluminum.
Copper clad aluminum sheet features
1) It has excellent machinability and can be used for shearing, bending, stretching, drilling, punching and other operations.
2) The joint surface of the copper layer and the aluminum layer is firmer, not easy to peel off, and the joint surface is not cracked by 90-degree bending.
3) The surface is smooth and clean, without dents, cracks or other defects.
4) The product has passed the ISO9001 international quality system certification.
5) The conductivity of 92% can completely replace pure copper, which is much lighter than the same volume of pure copper.
Applications of copper clad aluminum plate
Copper clad aluminum plates have a wide range of applications,including:power, communications, electronics, construction, thermal conductivity and other industries.The following introduces several typical applications of copper clad aluminum plate:
Copper clad aluminum bimetallic washer
In power equipment, if copper and aluminum are directly connected, electrochemical corrosion will occur, resulting in increased resistance and local circuit heating, resulting in power accidents. Copper-aluminum composite gaskets can effectively solve this problem. It is mainly used in reactors, Lithium batteries, electrical parts, etc.
Copper clad aluminum sheet for decorative materials
Copper has beautiful color, beautiful appearance, and strong corrosion resistance. Curtain walls and copper doors made of aluminum as the base layer and copper as the cladding can be used to replace pure copper products, because the main raw material is aluminum, and aluminum is light. , which can significantly reduce the difficulty of processing and installation.
Copper clad aluminum sheet for heat dissipation
With the development of light weight and miniaturization in the electronics, communication and transportation industries, the heat dissipation problem of high energy density has become more and more prominent, such as the inverter conversion of electric vehicles, the heat dissipation of PLC chips, and the high-power LED searchlights, all of which are very small. The volume of the aluminum alloy generates huge heat, and the copper-aluminum composite radiator is an ideal material to solve such problems. It not only exerts the thermal conductivity of copper, but also exerts the heat dissipation and light weight of aluminum, which not only achieves high energy density The miniaturization also realizes the lightweight of the cooling system.
Copper clad aluminum busbar
Copper clad aluminum buabars are mainly used in conductive industries, such as high and low voltage distribution cabinets, complete switches, busbars, electrolytic cells, etc. It not only solves the problem that copper and aluminum are easy to oxidize and the oxide film is difficult to eliminate, but also solves the problem of copper and aluminum. It is easy to produce intermetallic compounds at lower temperatures, and has excellent mechanical properties. The properties of bending, drilling and punching are the same as those of pure copper.
Copper to aluminum transition plates
The traditional copper to aluminum transition plates are generally prepared by flash welding, friction welding, brazing and other processes. The mechanical properties, reliability and electrical conductivity of the product joints have quality risks and potential safety hazards. The copper to aluminum transition plate is developed by our company. The new material is an ideal copper to aluminum transition plate.
Substrate for heat dissipation used in Led
LED products have the advantages of energy saving, power saving, high efficiency, fast response time, long life cycle, environmental protection and so on. Then 15% of the input power of high-power LED products will be converted into light, and the remaining 85% of the electrical energy will be converted into heat energy, thus affecting the product life cycle, luminous efficiency and stability.
The copper clad aluminum heat dissipating substrate is an ideal new material that can improve the thermal conductivity and heat-dissipation efficiency of the LED chip, giving full play to the good thermal conductivity of copper and the good heat-dissipation performance of aluminum.
Copper clad aluminum connection used for lithium battery
The copper clad aluminum connection can realize the safe, reliable, light weight, simple series and parallel connection of lithium battery packs, high composite strength, metallurgical bonding between copper and aluminum, no contact resistance between copper and aluminum, and stable and reliable quality.
