copper clad aluminium foil

Copper has good conductivity and thermal conductivity, and has strong corrosion resistance. Therefore, copper and its alloys have been regarded as the preferred materials for conductivity and thermal conductivity. However, the world's copper resources are relatively scarce, and China's copper deposits are far lower than the world's average level. At the same time, China is a copper consuming country. In recent years, China's copper consumption has always been the first in the world. In 2011, the copper consumption of the power cable industry alone reached 4.84 million tons, and the copper used for electrical purposes has always been high-grade copper. As a result, the price of copper is getting higher and higher. People have to find other materials to replace copper to solve the copper resource and reduce the cost. China is rich in aluminum resources. Aluminum products can not only meet domestic demand, but also export overseas every year. Its price is several times lower than that of copper. Moreover, aluminum is also a good conductor of electricity and heat, with good corrosion resistance.

In conclusion, it is a very ideal method to replace copper with copper aluminum composite materials, which can greatly save the copper resources that are relatively scarce in China.

Copper clad aluminum foil, as a kind of composite material, integrates the physical, chemical, mechanical and price differences of copper and aluminum. It not only has the advantages of high conductivity, high thermal conductivity, low contact resistance and beautiful appearance of copper, but also has the advantages of light weight, corrosion resistance and economy of aluminum. It is a new composite material with excellent comprehensive performance and has been widely used in electronic, electrical, metallurgical equipment Automotive energy and household appliances.

Material type: copper clad aluminum foil (0.02-0.2mm)
Composite copper layer thickness ratio: 16% - 22% copper thickness ratio on both sides
Copper mass ratio: 33% ~ 65%
Brand related: T2 / 1060

Copper clad aluminum foil, copper aluminum bonding degree is stable at 100%. The bonding strength is > 40MPa, which can be used for punching, drilling and other processing. The bonding strength of copper aluminum interface is much higher than the welding strength requirements of general electronic components, and it can easily withstand several kilograms of tension without cracking. The products can widely replace calendered copper foil and help the new energy industry and electronic technology industry to save costs and increase efficiency
