Product Description

Aluminium-Steel Bimetal Clad Flange
Aluminum bimetal -----Structure Transition Joints

Cladding is a process in which a minimum of two different types of metal are joined to form an inseperable "laminated" material. These Clad Materials are produced through our Cold Rolled Bonding process, which we developed more than 50 years ago.

CHALCO aluminum's structure transition joints aluminum bimetal are commonly used to make a welded and maintance free connection between alloyed aluminum components and steel structures in the shipbuilding, railway and automotive industry.

The major shortcomings of rivets and bolts are that they require holes to be drilled, need special insulators and require regular assembly inspection. Any removal of material, such as drilling holes, also weakens the metal.
 
Aluminum bimetal--Structure transtion joints are an indisputably better option because they eliminate crevices and have shown to limit crevice corrosion. Aluminum bimetal - Transition joints require no extra hardware, which allows engineers to stream-lin, their designs and shave off extra weight..
