Hisea's welding type aluminum anode is a high-efficiency sacrificial anode designed for the cathodic protection of steel structures in seawater and brackish water environments. Featuring pre-welded steel cores or mounting plates, they are ready for direct attachment to hulls, offshore platforms, and other marine assets, providing long-lasting, maintenance-free corrosion protection.

Key Advantages & Specifications‌

‌Superior Electrochemical Performance:‌

‌High Capacity:‌ Aluminum anodes provide approximately ‌3 times the current capacity‌ (in Ah/kg) compared to traditional zinc anodes of the same weight, meaning longer service life or fewer anodes required.

‌Efficient Protection:‌ Provides reliable protection in standard seawater and brackish water.

‌Economic & Operational Benefits:‌

‌Cost-Effective:‌ Typically more economical than zinc anodes on a cost-per-unit-capacity basis.

‌Lightweight:‌ Aluminum alloy is lighter than zinc, reducing the overall weight added to the structure—a critical factor for vessels and floating platforms.

‌Environmental & Safety Compliance:‌

‌Cadmium-Free & Eco-Friendly:‌ Manufactured without harmful heavy metals like cadmium, making them a safer choice for the marine environment.

‌Technical Specifications :‌

‌Common Alloys:‌ Al-Zn-In series .

‌Electrochemical Capacity:‌ ~2500 Ah/kg.

‌Open Circuit Potential:‌ Approx. -1.05V to -1.10V vs. Ag/AgCl/seawater.

‌Consumption Rate:‌ ~3.5 kg/A·year.

Primary Applications‌
Welding type aluminum anodes are the preferred choice for cathodic protection in:

‌Ship & Boat Hulls:‌ External hull plating, rudders, and keels.

‌Offshore Structures:‌ Jackets, piles, and subsea components of oil & gas platforms.

‌Seawater Intake Systems:‌ For power plants and industrial facilities.

‌Harbor & Coastal Steelwork:‌ Lock gates, sheet pilings, and jetties.

‌Ballast Tanks & Internal Surfaces
