Trimetal Electric Power Joints “Al-Ti-Steel”
Trimetal Electric Power Joints “Al-Ti-Steel” are normally used in the construction of the anode holder bar to ensure the proper technological cladding of steel and aluminum by means of the titanium layer which excludes the formation of fragile intermetallic compounds of aluminum and iron.
The device operates in high temperature media (around 350 °С) and requires the confirmation of the guaranteed service life. Tests were run on samples manufactured by the order of the Nadvoitski Aluminum factory belonging to the company Rusal. All parameters were properly confirmed by the Inspection Protocol.
Such Trimetal Electric Power Joints are produced by Nobelclad (France). In Russia, Power Joints of a different type seem to be more common. Therefore, this device falls into the category of perspective solutions.
