Lightweighting vehicles and molds through dissimilar metal joining! Explosive bonding joints and clad.
Achieve high durability and lightweight design with structural dissimilar material joints that enable strong bonding between lightweight metals such as aluminum, magnesium, titanium, and steel materials!
Asahi Kasei Corporation has developed an explosive welding technology that utilizes the instantaneous high energy generated during the explosion of explosives to metallurgically join dissimilar metals at room temperature. This product ensures durability by firmly joining lightweight metals (aluminum, magnesium, titanium) with steel materials, significantly contributing to the weight reduction of vehicles, ships, molds, and more. ■STJ(R) "Structural Transition Joint" STJ(R) is a compact and highly durable structural joint that enables the welded integration of aluminum alloy structures with carbon steel or stainless steel components. ■Flame-retardant Magnesium Alloy Joint A structural joint of flame-retardant magnesium alloy with aluminum alloy or stainless steel. *For more details, please refer to the PDF document or feel free to contact us.

Company information
BA Clad is a clad steel plate manufactured by Asahi Kasei using the explosive cladding method, and it has received high praise in various fields since its release. The explosive cladding 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, cryogenic joints, ultra-high vacuum joints, and structural joints for ships and LNG tankers. We offer 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, which 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 bonding, brazing, plating, and thermal spraying.
