Advanced Ultrasonic Welding Solutions For Aluminum Wire
Copper has good electrical and thermal conductivity and good ductility, so many automotive wiring harnesses use copper wires. However, the weight of copper is 3.3 times that of aluminum. In the current environment of energy saving and emission reduction, lightweight aluminum conductors for automobiles have great advantages. At present, the price of copper in shortage of resources has skyrocketed, and the price of copper will be three times that of aluminum. Aluminum wires also have great advantages in cost reduction. Therefore, more and more automotive wiring harness products on the market now use aluminum wires. After several years of technological development, some technical problems of aluminum wires have been well solved. These aluminum wire connection solutions have been fully proven in some production vehicles.
Now we share with you the solution of ultrasonic welding aluminum wire and copper terminal:
First of all, the aluminum wire will choose the aluminum wire with high temperature resistant silicone skin, with or without shielding, it will be selected according to the application environment of different products; at present, there are not many large square aluminum wires on the market that can meet ultrasonic welding; in addition, the copper terminals will be silver-plated deal with.
In ultrasonic welding, the stability of the aluminum wire to the welding machine will be higher, especially if the aluminum wire is too penetrated, it is easy to stick, and the adhesion will affect the mass production efficiency and the yield of the welding product.
After years of experience accumulation and technological innovation, Altrasonic has a very good solution for ultrasonic welding of aluminum wires. Welcome to consult our sales consultant.
