China Bimetallic Aluminum Clad Steel Plate

Explosive Bondingmetal dynamic cladding technology uses high energy from explosive detonation 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.Advantages compared with single metalExplosive 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 Bimetal Piece IntroductionPhohom's Aluminum Clad Steel is commonly used to make a welded and maintenance free connection between alloyed aluminum components and steel structures in the shipbuilding, railway and automotive industry.
Aluminum Clad Steel is an indis-putably better option because they eliminate crevices and have shown to limit crevice corrosion. It requires no extra hardware, which allows engineers to stream-line their designs and shave off extra weight.

Aluminum Clad Steel
Although some engineers have had success in spot welding steel and aluminum together, it has largely been considered difficult to achieve reliable, continuous welds directly between the two dissimilar metals. That changed, however, when explosion welding was developed for doing that very thing.
Explosive welding is considered to be a solid-state welding process that uses controlled explosive energy to force two or more metals together at high pressures. The resultant composite system is joined with a high-quality metallurgical bond.
With other advantages like high efficiency, low cost and less requirement in equipment, explosive welding would be the optimal choice for welding aluminum to steel.
Its technical performance index as following: shear strength≥ 300N/mm2;according to the special requirements for products, such as the clad plate used for Petrochemical hydrogenation unit, conjoint ratio can reach 100%; interface shear strength>196MPa; the thickness of cladding layer 1~2mm, can be more thicker, the thickness of backer ≥1mm. The size of clad steel plate is not limited by explosive welding technical.
