Steel aluminum transition joints

Apr 04, 2023

Steel aluminum transition joints is a new kind of structural material with special properties. Due to some characteristics of aluminum and steel, especially the difference of melting point and strength, as well as the characteristics of a lot of intermetallic compounds formed between them, it is difficult to make them into composite materials by conventional process. This makes explosive welding the best new technology for large-scale manufacturing of steel aluminum structural transition joint.
In the manufacturing of marine ships, the application of aluminum alloy is mainly to connect the aluminum structural parts with the steel deck. In the past, this connection with rivets or screws can not guarantee the sealing performance, thus accelerating the corrosion in seawater. Steel aluminum transition joint is adopted, and the service temperature of this joint is generally less than 300 ℃. If titanium is added between aluminum and steel, that is, aluminum titanium steel transition joint is used. When the service temperature reaches 450 ℃, the bonding strength and conductivity remain unchanged. Generally, this kind of joint is used to connect steel ship deck and aluminum alloy superstructure



Features: steel aluminum structural transition joint combines the characteristics of bright steel surface, easy cleaning, light aluminum mass and high thermal conductivity, and has excellent conductivity and corrosion resistance.
Application fields: shipping, transportation, transition joint of low temperature factory, cathode and anode materials in metallurgical electrolysis project.
