Ship Hull Aluminum Anode
Ship Hull Aluminum Anode
The aluminum alloy anode can prevent the corrosion of steel structure in seawater, widely used for the anti-corrosion of the ship hull, pressurized water tank, seawater pipeline, port and terminal facilities, marine engineering, drilling platform, condensator and pipelines in soil. The performance of aluminum anode is influenced by the chemical composition of the alloy, so we offer different composition of aluminum alloys to meet our customer requirements.
Implementing Standard
GB/T 4948-2002
Main Performance
The driving voltage is low; light weight; high current efficiency.
Note: our company can also design and produce all kinds of special specifications and properties of aluminum alloy sacrificial anode according to the different needs of customers.
