Metal dynamic cladding technology uses high energy from explosivedetonation to produce a metallurgical weld between metal plates. It can produce high voltage pulse energy, pushing cladder collide with backer at a specific velocity and impact angle. That process produces much bigger stress than the yield strength of metal material. All these happen at instantaneous moment and simultaneously infinitesimal adjacent area of collision point of limited loading stress of materials, realizing wavelike metallurgical weld of two materials.
Explosive bonding is free from materials shape, thickness and areas. It realizes metallurgical connection between dissimilar metals. Metallurgical bonding ensures no distributed transverse crack. It makes dissimilar metal combinations possible which are conventional impossible to weld while original metal properties maintain and joint bond stronger than the weakest material. And it saves rare metals and cost effectively, thin layer of expensive material cladded on a thicker layer of cheap material.
Phohom’s Copper Cladding Aluminum Plate
Coppercladding aluminum platehave high electrical and heat conductivity, which makes them the basic materials for electric power transmission and heat transfer engineering. With the shortage of copper resource, substituting aluminum for copper is becoming an inevitable trend. Compared with copper, aluminum has poor welding performance, bigger surface contact resistance, so it is still difficult to use aluminum instead of copper making many parts directly. Cladding a layer copper on the surface of aluminum plate, the product copper-aluminum clad plate can improve surface contact resistance and welding properties of aluminum, which reduces the cost and weight.

Many important parts of heat exchanger, electric transmission, and electrical equipments, such as cooling fins, collector tubes, transition plates, etc. are normally made of copper-aluminum clad metals. In the same way, copper-clad-aluminum conductive wire is also a good application of metal clad metals in electric power, electronic industry. Copper-clad-aluminum conductive wire overcomes the problems of contact and creep of pure aluminum wires; compared with the pure copper wires, it can reduce the expensive copper consumption.
Applications for electric conduction
copper-aluminum clad metals used as transition materials for low voltage electric appliances; transformer belts; solar panels, etc.; copper-aluminum clad terminals, copper-aluminum clad transition plates, copper-aluminum clad clamps, copper-aluminum clad gaskets, etc, for high voltage distribution; copper-aluminum clad transition joints, copper-aluminum clad conductive bars; copper-aluminum clad electrodes; copper-aluminum clad conductive arms, etc, for electrolysis unit
Applications for heat conduction
Car water tank belts; cooling fins; collector tubes; hot food tablewares; etc
