Copper-clad aluminum composite material "CCAC"
Copper-aluminum composite material "CCA" developed by Applied Composite Material (ACM) Inc.
For lightweighting copper components! Copper-based parts that couldn't be aluminumized in the past might be achievable with CCA!
CCAC (Copper Clad Aluminum Composite) is a new type of copper-aluminum clad material that uses isothermal processing technology (patented internationally) to achieve a metallurgical bond of copper to an aluminum core. While retaining the excellent properties of copper, such as conductivity, it also combines the advantages of aluminum, being lightweight and low-cost. Unlike clad materials made by bonding dissimilar metals, it features a shape where copper completely covers the aluminum. It boasts excellent conductivity, thermal conductivity, heat dissipation, solderability, and plating properties, along with high ductility and ease of processing. It is metallurgically bonded through a controlled high-temperature isothermal process, which also prevents oxidation. In addition to drilling and bending, it can be adapted for processing operations such as deep drawing, twisting, and cutting.

Price information
When compared to the unit weight prices of copper and aluminum individually, they are expensive, but since the weight can be reduced even with the same surface volume, it is possible to achieve overall cost reduction. For more details, please contact us.

Applications/Examples of results
It is used in the automotive, aerospace, electrical and electronic equipment industries, and many other industries. In particular, it is possible to achieve weight reduction by switching from copper to materials that conduct electricity. Additionally, I believe there have been many instances in the past where the fluctuation of copper prices led to considerations for aluminum. With this CCA, it is possible to secure conductivity that significantly exceeds that of aluminum, thereby expanding the possibilities for realization.
Detailed information
-
The components that used pure copper busbars have been changed to CCA. It was necessary to increase the size slightly compared to when using pure copper, but we were able to reduce the weight by about half, successfully achieving weight reduction and a total cost reduction.

Company information
<Metal Materials Trading Division> With a rich inventory and four slitting facilities, we supply from the Higashi-Osaka Coil Center to the entire country. We specialize in the sales of copper alloy materials and non-ferrous metal materials. We are also actively proposing the next-generation copper-aluminum clad material "CCAC" in collaboration with Applied Composite Material Corp. <Metal Processing Division> We excel in processing small quantities of various metal pipes. Our diverse technologies include coil winding, R-bending, various bending processes, and welding. We handle everything from one-off parts used in heat exchanger components and machinery to larger quantities for automotive, consumer, and housing equipment. In the world of bending processing, where small lots are common, the presence or absence of molds becomes quite important. We mix our own molds and equipment with those from partner factories to provide tailored proposals. Additionally, our NC automatic lathe precision cutting processing leverages the procurement advantages unique to Tatsumiya, which has a metal materials trading division, enhancing customer satisfaction through technical expertise, procurement capabilities, and cost efficiency. With over 90 years of establishment as a processing trading company, we view the 100-year mark as a milestone and will continue to build a great company in the future.
