The Zinc Anode 620 is the industry workhorse for localized protection on steel hulls, sea chests, and side thrusters. When sourcing, demand a Mill Certificate verifying the Cadmium (0.07%) and Iron (<0.005%) levels. Standard “Hardware store” zinc will not provide the 780 A·h/kg required for marine service.
Always verify the exact weight (kg/lbs) with your supplier, as "620" is a shape code, not a universal mass standard.

Protecting Your Assets: The Zinc 620 Anode Deep Dive If you’re operating in marine environments, you know that saltwater is the enemy of metal.
To keep your hulls, tanks, and pipelines from dissolving, you need a sacrificial lamb—or in this case, a sacrificial metal. The
is a powerhouse in this category, specifically designed to take the hit so your infrastructure doesn't have to. What is a Zinc 620 Anode?
The "620" designation typically refers to specific military or industrial standard compositions (often aligned with MIL-DTL-18001L
) used for cathodic protection. These anodes are made of high-purity zinc alloyed with small amounts of aluminum and cadmium to ensure they corrode evenly and don't "passivate" (develop a crust that stops them from working). Key Technical Specifications Based on industry standards like those found on , here is what you can expect from a 620-series datasheet: Potential: Approximately
(vs. Ag/AgCl reference electrode). This negative potential ensures it remains the "active" part of the circuit. 780 Amp-hours per kilogram (354 Ah/lb). Efficiency: 90% to 95% TSEWG TP-17
. Unlike other metals, zinc provides a very steady, predictable current output. Consumption Rate: 10.7 kg (23.5 lbs) per Amp-year. Why Choose Zinc Over Aluminum or Magnesium? Fisheries Supply
notes that aluminum is becoming more popular, Zinc 620 remains the gold standard for pure saltwater for several reasons: Reliability:
It has a long track record in military and commercial shipping. No Over-Protection: Magnesium can sometimes be
active, causing paint blistering on hulls. Zinc is "gentle" enough for most coated surfaces. Self-Cleaning:
The 620 alloy is designed to shed its corrosion products, ensuring a fresh reactive surface is always exposed to the water. Maintenance and Replacement
Don't wait until the anode is gone to replace it. According to the Barnacle King's Guide
, you should replace your Zinc 620 anodes when they have worn down to 50% of their original size. In most marine conditions, this occurs every 6 to 12 months. Application Tips Proper Contact:
Always ensure a metal-to-metal connection. Never paint over your zincs, as this effectively "insulates" them and stops the protection. Placement: For vessels, BoatCorrosion.com
recommends installing plates on the bottom of the hull, specifically between the transom and the rear third of the vessel. Are you planning a haul-out or scheduled maintenance?
Check your current consumption rates to see if switching to a higher-capacity Zinc 620 could extend your service intervals. customized maintenance schedule

Below is a datasheet breakdown for the most likely candidate: the Energizer Industrial 620 (EN95) Zinc Battery, along with technical details on Zinc Anode composition in general.
The "620" typically denotes the net weight (0.62 kg or 1.37 lbs) of zinc, though some industrial suppliers use the code for a 620 cu. cm volume. The most common commercial variant used in North America and Europe is the Hull Mount 620:

Below is a comprehensive technical breakdown of the specifications, applications, and installation guidelines for a standard 620-series zinc anode. ⚓ Zinc Anode 620 Technical Specifications
The "620" designation typically refers to a specific weight or size class in the marine industry, often weighing approximately 10–12 lbs (4.5–5.5 kg) depending on the specific manufacturer (e.g., Martyr, Camp, or Tecnoseal). Physical Dimensions (Standard) Length: 12 inches (305 mm) Width: 3 inches (76 mm) Thickness: 1.25 inches (32 mm) Bolt Centers: 6 inches (152 mm) — Common for "620" series Weight: ~11.5 lbs (Zinc alloy) Chemical Composition The "Zinc Anode 620" is not a universal anode
To meet MIL-A-18001K (the gold standard for zinc anodes), the alloy must adhere to these strict percentages: Zinc (Zn): Remainder (approx. 99.3%) Aluminum (Al): 0.10% – 0.50% Cadmium (Cd): 0.025% – 0.07% Iron (Fe): 0.005% Max Lead (Pb): 0.006% Max Copper (Cu): 0.005% Max ⚡ Performance Characteristics
The 620 anode works via Galvanic Corrosion. It possesses a lower (more negative) electrochemical potential than the steel it protects.
Open Circuit Potential: -1.05 Volts (relative to Ag/AgCl reference electrode).
Electrochemical Capacity: 780 Amp-hours per kilogram (Ah/kg). Consumption Rate: Approx. 11 kg (24 lbs) per Amp-year. Density: 7.13 g/cm³. 🛠️ Key Applications
The 620 series is a "medium-heavy" anode, making it ideal for: Commercial Hulls: Tugs, barges, and fishing vessels. Ballast Tanks: Protecting internal steel from salt water.
Piers and Pilings: Mitigating corrosion on submerged infrastructure. Heat Exchangers: Large-scale industrial cooling systems. 📝 Installation & Maintenance Best Practices
To ensure your 620 anode provides maximum protection, follow these rules: Electrical Continuity
Never Paint Anodes: Paint insulates the zinc, rendering it useless.
Metal-to-Metal Contact: Ensure the mounting studs are wire-brushed and clean before bolting. Replacement Schedule
The 50% Rule: Replace the anode once it has consumed 50% of its original mass.
Active Monitoring: If an anode looks brand new after six months in salt water, it is likely not working due to poor electrical contact. Environmental Suitability Salt Water: Excellent (Zinc is the industry standard).
Brackish Water: Good (Aluminum may be preferred for low-salinity).
Fresh Water: Poor (Zinc can form a "crust" of oxide that stops the current; use Magnesium instead). If you'd like, I can help you:

Summary of Zinc Anode 620 The Zinc Anode 620 is a specialized sacrificial galvanic anode designed for cathodic protection, primarily used to prevent corrosion of buried or submerged metal structures. 🛠️ Key Technical Specifications
Based on standard industrial datasheets, the 620 series typically adheres to the following profiles:
Material Composition: High-purity zinc alloy (often ASTM B418 Type II for soil or Type I for saltwater).
Open Circuit Potential: Approximately -1.10 Volts relative to a Cu/CuSO4 reference electrode.
Capacity: Theoretical current capacity of ~820 Ah/kg (372 Ah/lb). Efficiency: Typically ranges from 90% to 95%. 📦 Packaging & Installation
These anodes are often "pre-packaged" to ensure consistent performance in high-resistance soils:
Backfill Mixture: Usually a 50/50 mix of Gypsum and Bentonite.
Purpose: The backfill lowers contact resistance and moisture retention around the anode.
Connection: Supplied with a standard lead wire (e.g., 10ft of #12 AWG THHN/THWN) for connection to the structure. 🌊 Primary Applications
Underground Pipelines: Protecting coated steel pipes from soil corrosivity.
Storage Tanks: Corrosion prevention for the external bottoms of grounded tanks.
Marine Environments: Ideal for structures in saltwater or brackish water where aluminum or magnesium might over-protect.
Grounding: Often used as earthing electrodes to mitigate AC interference. 🛡️ Why Zinc?
Zinc is chosen over magnesium in specific scenarios because it has a lower driving voltage. This prevents "over-protection," which can lead to hydrogen embrittlement or coating disbondment on certain high-strength steels.
