Product Description
Commonly used specifications: thickness 3-10mm, copper layer thickness ratio 10-40%.
Currently, the negative electrode metal poles used in power lithium batteries are mainly copper-aluminum composite materials produced by the friction welding process. However, this process has many disadvantages. Our company uses continuous casting Copper-aluminum composite materials produced by rolling composite patented technology effectively solve the above problems. A comparison of the two processes is as follows:

1 |
Bond strength |
Composite under high temperature, high pressure and oxygen-free conditions to achieve metallurgical bonding with high bonding strength |
There will be some "non-ideal bonding" defects on the friction welding connection interface , such as gray spots, cracks, lack of welding, inclusions, intermetallic compounds, misalignment, etc., which are prone to breakage during use. |

2 |
Productivity |
Industrialized large-scale continuous production with high production efficiency |
Single piece production, low production efficiency |
|
3 |
product consistency |
High product performance consistency |
Each product is produced individually, and product performance consistency is low. |
