Aluminium is used in shipbuilding in combination with steel to reduce the overall weight of the ship, while keeping the manufacturing cost reasonable, and improve the stability of the vessel structure.
Joining aluminium and steel is a challenge since the two metals cannot be welded together using conventional welding methods. Also, bolting the two metals together poses the risk of corrosion at the joint area. TriClad® Aluminium/steel is an explosively bonded transition joint specifically produced for shipbuilders to provide a reliable welded joint between the two metals.
Titanium International is the AUNZ representative of Merrem & La Porte of Holland for TriClad®.
