Product Description

Copper-Aluminum bimetals VS pure Copper: lower density, larger volume, lower cost. 

Our Copper-Aluminum Bimetal Composites material is a plating of copper on aluminum. The two metals are combined together through our patented technology which we called Oxygen-free Semi-molten rolling compound technology. This technology solves the technical problems of oxidation and eutectic of copper-aluminum composite. Our composites materials are tested in many ways and proven over many years as a replacement material for pure copper in some applications.
 
Compare to pure copper material, Copper-Aluminum Bimetal Composites materials advantages are below.
 
1. Cost down much: less copper materials, greatly reduce the cost by about 40%-50%.
 2. ​Lightweight: the density of Copper-Aluminum Composites is only 37%-40% of pure copper, greatly reduce the weight by about 50%.

The widely used copper-aluminum composite material concentrates the advantages of copper and aluminum, which not only has the advantages of copper such as high electrical and thermal conductivity, low contact resistance and beautiful appearance, but also has the advantages of light weight and corrosion resistance of aluminum. Therefore, Copper-aluminum composite materials are widely used in new energy vehicles, lithium batteries, Photovoltaic, communication base station, power equipment, electricity, heat transfer,  and other industries.
 
Copper-Aluminum Composites strips/sheets can be made as Copper-Aluminum Composites transition busbar, lithium battery connecting terminals, Copper-Aluminum Composites heat sink, Copper-Aluminum Composites filter cover for communication base station, etc.
 
Our products are hot sold to more than 20 provinces across the country, and also exported to The European Union, South Korea, Japan, USA, and other countries. 

Advantages of our Copper-Aluminum Bimetal Composites materials :
1. Lower Weight due to lower density.
2. Lower cost due to larger volume.
3. Goodthermal/electrical conductivity, Highly corrosion-resistant.
4. Good mechanical properties, easy for cutting/punching/bending/drilling, etc.
5. Simpler processing, good for Mass-production.
