China C71520 copper clad aluminum plate sheet Manufacturer
Copper clad aluminum plate, also known as copper-clad aluminum plate or aluminum-based copper-clad plate, is a double-sided copper-clad aluminum-based plate.
It uses aluminum alloy plate and copper-clad plate as the base material, and is made of composite aluminum alloy and copper plate through processing technology.
This kind of plate combines the advantages of aluminum and copper, such as aluminum’s light weight, good toughness, plasticity and electrical conductivity, and copper’s excellent electrical conductivity, thermal conductivity and corrosion resistance.
Copper clad aluminum plate are widely used in many fields. In the field of electronics and communications, it can be used as a high-performance substrate for circuit boards to manufacture high-reliability circuit boards, and is widely used in computers, communications, consumer electronics and other fields.
In addition, it can also be used as a heat sink for LEDs to improve the heat dissipation effect of LEDs and extend the life of LEDs.
During the production process, copper and aluminum plates usually require surface treatment, such as pickling, alkali washing and electrolytic treatment, before being coated to increase their adhesion.
The coating process often uses a lamination process to form a strong bond between the copper plate and the aluminum plate under high temperature and high pressure conditions. Afterwards, the copper-clad aluminum may also undergo heat treatments, such as annealing and solution treatment, to further improve its properties.
although copper clad aluminum laminate has many advantages, due to the different chemical properties of copper and aluminum, it may also cause electrochemical corrosion and is difficult to process, requiring a high level of processing technology and equipment.

copper clad aluminum plate
Copper clad aluminum plate is a composite material with excellent performance and wide application, playing an important role in electronics, communications, LED manufacturing and other fields.
What are the specific applications of copper clad aluminum plate in the electronics and communications fields?
1. Circuit board substrate
Copper clad aluminum plates can be used as high-performance circuit board substrates, taking advantage of the excellent conductivity of copper and the lightweight properties of aluminum to meet the circuit board’s needs for high conductivity, lightweight and good heat dissipation.
This is particularly important for circuit board manufacturing of computers, communication equipment and consumer electronics products, as it can improve the operating efficiency and stability of the equipment.
2. High frequency circuit
In high-frequency circuits, copper clad aluminum plates can reduce signal transmission delays and distortions and improve signal transmission quality and stability due to their lower dielectric constant and dielectric loss.
Therefore, it is often used to make high-frequency circuit boards, such as microwave circuit boards, radio frequency circuit boards, etc., and is widely used in wireless communications, satellite communications, radar systems and other fields.
3. Electromagnetic shielding
Copper clad aluminum panels have good electromagnetic shielding properties and can effectively prevent interference and radiation from electromagnetic waves on electronic equipment. In the manufacturing of communication equipment, it is often used as electromagnetic shielding material to improve the electromagnetic compatibility and reliability of the equipment.
4. LED heat dissipation
LED lamps generate a large amount of heat when working. If the heat dissipation is poor, the life of the LED will be shortened and its performance will decrease.
Due to its good thermal conductivity and heat dissipation performance, copper-clad aluminum plate can be used as a radiator material for LED lamps to improve the heat dissipation effect of LED lamps and extend their service life.
In addition, copper clad aluminum sheets can also be used to make electronic components such as capacitors and inductors, as well as communication equipment components such as antennas and filters.
Its excellent electrical and mechanical properties give it broad application prospects in these fields.
