- Description
The MARTYR Hull Anode with Steel Insert (Aluminium) is a heavy-duty sacrificial anode designed to provide effective cathodic protection for boat hulls, rudders, and submerged metal components. Manufactured using high-purity aluminum alloy, this anode is ideal for saltwater and brackish water environments, offering longer life and higher efficiency compared to zinc.
A key feature of this design is the cast-in steel insert (core), which enhances the mechanical strength of the anode and ensures secure mounting to the hull. According to MARTYR product specifications, inserts and straps are available in steel or aluminum, depending on application requirements, to improve durability and installation reliability.
MARTYR anodes are produced to meet or exceed U.S. Military Specifications, ensuring consistent corrosion protection and long service life in harsh marine conditions.
