We are a professional manufacturer of aluminum copper bimetallic strip，We have used the solid-liquid processing technology to apply for national patents. This technology is more solid aluminum-copper combination, more material saving, higher conductivity. Feature:
1.it not only has good heat dissipation, but also has good electrical conductivity, weldability and easy processing.
2. The use of advanced composite equipment, using continuous composite technology, with rapid vertical annealing process, control the middle layer of aluminum and copper composite interface diffusion layer, prepared high-performance aluminum copper bimetallic strip.
3. strict quality inspection system for surface quality, combined with aluminum copper bimetallic strip strength, resistivity, hardness and other properties of standard test.
4. good mechanical properties, the size of the product can be customized according to the requirements of the customer.
The application of aluminum copper bimetallic strip is widely used in electric power, general construction, shipping and other industries, the application in the power industry include the following:

Substation & Switchyard Bimetallic clamp and connectors
Oil & Vacuum Circuit Breakers Distribution
Cable lugs and cable end connectors
Isolators and switchgears
Overhead connectors
Flexible connectors
