A-magnetic armoring wire for submarine power cables
Bekaert a-magnetic armoring wire is a heavily galvanized, austenitic stainless steel wire used for protecting three phase submarine power cables.

Galvanized stainless steel has several important benefits of which a-magnetic behavior is the most important one. Stainless steel has a low permeability which reduces energy losses in the armoring by the cable’s magnetic field. Consequently, this property significantly increases the cable’s efficiency without needing to interfere with the cable design as is the case with other armoring solutions. 

A heavy zinc layer on austenitic steel offers an excellent resistance to pitting and crevice corrosion, making it perfect for marine applications. The combination of these features offers a much more predictable and reliable coating lifetime and performance compared to uncoated austenitic stainless steel solutions. Even when the zinc layer gets damaged, the surrounding zinc will act as a sacrificial anode and protecting the underlying stainless steel. Basically this wire offers the same corrosion protection in marine environment as the classic hot dip galvanized low carbon wires. 

The combination of these benefits makes Bekaert a-magnetic armoring wire the only full a-magnetic solution that combines excellent corrosion resistance with good processability.
