Aluminum Steel Composite Material Plate Sheet Transition Joints

Aluminum has excellent electrical conductivity and thermal conductivity, making it widely used in the electrical industry. Aluminum is non-ferromagnetic, which is an important characteristic for the electrical industry and the electronics industry.

The specific strength of some aluminum alloys is comparable to that of steel, and its specific stiffness exceeds that of steel. Therefore, aluminum alloy materials have been widely used in transportation, chemical industry, machinery, power, electronics and construction, especially in aerospace industry.

Aluminum Steel Composite Material Plate Sheet Transition Joints are a new type of structural material with special properties. Because of some properties of aluminum and steel, especially the difference in melting point and strength, and the fact that many intermetallic compounds are formed between them, it is difficult to make them into composite materials by conventional processes. This makes explosive welding the best way to manufacture large area aluminum steel composite materials.

In the manufacture of marine ships, the application of aluminum alloys is mainly to connect aluminum structural parts with steel decks. In the past, rivets or screws were used for this connection, which could not guarantee sealing, thus accelerating the corrosion of seawater media. The use of Aluminum Steel Composite Material Plate Sheet Transition Joints, the temperature of the joint is generally <300 ºC. If titanium is added between aluminum and steel, both aluminum-titanium-steel transition joints are used, the bonding strength and conductivity can remain unchanged when the service temperature reaches 450 ºC. Generally, this kind of joint is used to connect the steel deck of ship with the superstructure of aluminum alloy. This process of aluminum-steel transition connection can completely replace riveting and completely solve the problem of aluminum-steel transition connection.Aluminum Steel Composite Material Plate Sheet Transition Joints are also widely used in offshore containers, with good corrosion resistance and attractive low weight, widely replacing rivet joints, having good shear strength, and withstanding salt testing.

Aluminum alloy-titanium-low carbon steel (stainless steel) three-layer composite materials have been widely used in frigates and other ships cabins, ship side as well as masts, liquefied natural gas tanks and so on.
