High Conductivity Copper-Clad Aluminum Bus Bar 5*40 mm

Product Description

Product Description

Copper clad aluminum bars are made of a composite of copper and aluminum materials, with copper and aluminum contents of 30% and 70%, respectively. This ratio can ensure the strength and thermal conductivity of the product, making them particularly suitable for applications that require high strength and thermal conductivity. The copper clad aluminum strip adopts a special production process to tightly combine copper and aluminum materials, inheriting the excellent performance of copper and aluminum, and achieving a dual effect.

Specifications
The size of copper clad aluminum bars can be customized according to different customer needs. Common sizes include 15x100, 20x150, 25x200, etc. They can also be customized according to different application scenarios. In addition to providing standard sizes, we can also customize according to customer needs to meet their different needs.

Production process
Our copper clad aluminum production process is very strict. From material selection to product molding, copper and aluminum materials need to undergo special treatment to make their bonding more tight. After special processing, the creep deformation is small, and the performance is close to that of copper, overcoming the fatal weakness of aluminum busbar. Its reliability is the same as that of copper busbar, and its performance is fundamentally different from that of aluminum busbar. It can replace copper busbar, but the price is significantly reduced. Then, we use extrusion equipment and obtain the required size through extrusion.

Advantage
The surface of the copper aluminum composite busbar is copper, therefore, its oxidation resistance is the same as copper. Mutual overlap refers to the overlap between copper and copper, and its electrical life is the same as that of copper bars when powered on for a long time. Another advantage is low density, light weight, and tight bonding with other metals. This makes copper clad aluminum bars suitable for various fields, such as power equipment, transformers, and switchgear. One of the advantages of copper clad aluminum bars is their excellent thermal conductivity. The combination of copper and aluminum materials makes it perform well in high temperature and high pressure working environments, and has excellent stability. Copper clad aluminum bars can withstand high temperature, high pressure, and severe cooling conditions without deformation and cracking.


In summary, the main purpose of copper aluminum composite busbar is to address the fatal weakness of aluminum busbar in terms of conductivity, while ensuring safe, reliable and long-lasting use, and reducing manufacturing costs. The high strength and thermal conductivity of copper clad aluminum bars are becoming increasingly important in the market for promotion. This copper clad aluminum strip can play a huge role in various industrial and construction fields, and its flexibility, customizability, high strength, and excellent thermal conductivity make it an ideal choice in thermal control systems.
