Copper Cadding Aluminum Sheet Transition Joint

Copper Cladding Aluminum Sheet Transition Joint

Product Introduction

The Copper Cladding Aluminum Sheet Transition Joint is an advanced composite material that combines the superior conductivity of copper with the lightweight and corrosion-resistant properties of aluminum. This innovative material is designed to provide seamless transitions between copper and aluminum components in various industrial applications, ensuring optimal performance and durability. Manufactured using advanced explosive welding technology, this product delivers exceptional mechanical strength, electrical conductivity, and long-term reliability.

Preparation technology of copper-aluminum plate transition joint
1. Explosive welding method
Explosive welding is a common and mature copper-aluminum composite technology. It uses the instantaneous high energy of explosives to drive the metal plates to collide at high speed and complete metallurgical bonding within nanoseconds. This method has the following characteristics:
High bonding strength and no obvious oxide layer on the interface;
Suitable for large-area plate composite;
Relatively high cost and high safety control requirements.
2. Rolling composite method
Hot rolling or cold rolling is used to physically press the copper plate and the aluminum plate under high pressure. This method is suitable for mass production, but it has strict requirements on surface cleanliness and rolling parameter control. Its advantages are:
The process is relatively safe;
Suitable for thin plate composite;
The interface bonding quality is slightly lower than explosive welding.

Technical Specifications

Advantages of copper-aluminum plate transition joint
1. Bridge between dissimilar metals
The greatest value of the copper-aluminum plate transition joint is that it establishes a stable "bridge" between copper and aluminum, avoiding electrochemical corrosion caused by direct connection. Copper and aluminum are far apart in the electrochemical sequence. Direct connection is very likely to produce corrosion reactions due to potential difference, while the composite interface formed by the copper-aluminum plate transition joint avoids this problem.
2. Improve the efficiency of conduction
The copper-aluminum plate transition joint can effectively reduce the contact resistance and ensure the stability of current transmission. Under high current conditions, such as the substation busbar connection system, the use of copper-aluminum plate transition joints can reduce power loss and improve operating efficiency.
3. Reduce costs and lightweight structure
The density of aluminum is only one-third of that of copper, and the price is also lower. Through the copper-aluminum plate transition joint, part of the copper material is replaced by aluminum, which not only reduces the overall material cost, but also reduces the weight of the structure, which is conducive to the miniaturization of equipment and energy conservation and emission reduction.
Application areas of copper-aluminum plate transition joints

1. Power transmission and distribution system
In high-voltage power transmission and transformation equipment, a large number of copper-aluminum plate transition joints are used to connect aluminum cables with copper busbars and terminal blocks. This connection method not only ensures stable electrical performance, but also effectively extends the life of the equipment.
2. Electrolysis and metallurgical industry
In the electrolytic cell plate system, copper is used for conduction and aluminum is used for structural support. The transition through the copper-aluminum plate transition joint can meet the dual needs of conductivity and mechanical strength at the same time.
3. New energy vehicles and energy storage systems
In new energy vehicle power battery packs, BMS systems, and energy storage modules, copper-aluminum transition joints are used to connect battery copper bars and aluminum shells to achieve efficient and safe conductive channels, which is an important part of lightweight electric system design.
