Electrode materials and cladding for heat sinks that achieve low cost and lightweight.
We achieve cost reduction and weight reduction without compromising the material properties in large current contact materials, electrode materials, and heat exchange materials.
By replacing copper used in materials such as high-current contact materials, electrode materials, and heat exchange materials (heat sinks) with "copper/aluminum clad," we respond to the needs for cost reduction and weight reduction. Additionally, our explosive crimping technology is a cold joining method that does not apply heat to the materials, making it difficult for impurities such as alloy layers to form at the bonding interface between copper and aluminum. This results in low electrical resistance and conductivity close to the theoretical value of the materials. ■ ETJ(R) Electrical Transition Joint 【Features】 1. Excellent electrical properties. 2. Superior mechanical properties. It has high bonding strength and demonstrates robust characteristics in bending and tensile tests. 3. Excellent heat resistance. The bonding strength does not change even after 5,000 cycles of thermal fatigue testing at 250°C and 25°C. 4. Regarding electrocorrosion: Our clad is fully bonded, preventing electrolytes from entering the interface, which allows for the prevention of electrocorrosion by only protecting the externally exposed surfaces with paint. *For more details, please refer to the PDF materials or feel free to contact us.

Company information
BA Clad is a clad steel plate manufactured by Asahi Kasei using the explosive welding method, and it has received high praise in various fields since its launch. The explosive welding method utilizes the enormous energy released during an explosion to instantaneously bond metal plates together, thereby producing clad steel plates. BA Clad is used for plants and equipment in the chemical industry, petroleum refining, petrochemicals, and power generation, and is exported widely both domestically and internationally, either as flat plates or various components. It is used as corrosion-resistant and heat-resistant structural materials for power plant condenser tube sheets, heat exchanger tube sheets for chemical plants, shells, and end plates, among others, and its applications are continually expanding to include rolling mill liners, electrodes, ultra-low temperature joints, ultra-high vacuum joints, and structural joints for ships and LNG tankers. We propose solutions related to metal joining (dissimilar metal joining, similar metal joining) and cladding. We can provide joining characteristics such as material properties, joining strength, minimization of alloying at the joining interface, and joining area that are difficult to achieve with other joining methods, such as various welding techniques, diffusion bonding (roll bonding, HIP, etc.), friction joining (friction welding, friction stir welding (FSW)), electromagnetic pressure welding, brazing, plating, and thermal spraying.
