Installation guidance (concise)

Ensure good electrical contact between anode and structure (clean mating surfaces).
Use appropriate non-reactive fasteners (bronze, stainless steel) or cast-on studs.
Position to provide even current distribution; avoid trapped air/gaps.
Allow space for expected erosion; calculate number and mass of anodes from design current and desired service life:
- Required mass (kg) = (Design current, A × Time, hours) / (Anodic capacity, Ah/kg)
Follow applicable marine/cathodic protection standards and local regulations.

3. Electrochemical Performance Data (The Critical Datasheet Metrics)

This is the core of the zinc anode 620 datasheet. Do not purchase an anode without these values.

| Parameter | Value | Test Standard | |----------------------------|--------------------------------|---------------------| | Open Circuit Potential | -1.030 V (vs. Ag/AgCl/Seawater)| ASTM G97 | | Closed Circuit Potential| -0.980 V to -1.010 V (vs. Ag/AgCl) | ASTM G97 | | Effective Current Capacity | 780 A·hr/kg (minimum) | NACE TM0190 | | Actual Consumption Rate | 11.8 kg/A·year | Theoretical | | Anode Efficiency | 95% (Minimum) | NACE TM0190 | | Driving Voltage (vs Steel)| 0.25 V (Seawater) | N/A |

2. Chemical Composition (Per ASTM B418 Type I & II)

The performance of a zinc anode is entirely dependent on its purity. Impurities (iron, copper, lead) cause passivation, where the anode stops working. The Zinc Anode 620 must meet strict limits:

| Element | Percentage (%) – MIL/ASTM Standard | |--------------------|-------------------------------------| | Zinc (Zn) | 99.86% Minimum | | Aluminum (Al) | 0.10% – 0.50% | | Cadmium (Cd) | 0.025% – 0.070% | | Iron (Fe) | 0.003% Max | | Lead (Pb) | 0.003% Max | | Copper (Cu) | 0.002% Max |

Why this matters: The Aluminum and Cadmium act as activators to ensure a uniform, film-free corrosion surface, guaranteeing a driving voltage of approximately 0.25V relative to steel.

1. What is the "Zinc Anode 620"?

The term "620" typically denotes a Hull or Brace Anode weighing approximately 6.2 kg (13.66 lbs) or measuring roughly 620 mm in length depending on the manufacturer's code. However, the industry standard for the “620” profile most commonly refers to a trapezoidal or rectangular bar anode used predominantly on ship hulls, heat exchangers, and water box applications.

Standard Dimensions (Typical for 620 Profile): Zinc Anode 620 — Datasheet Overview Recommendation If

Length: 620 mm (24.4 inches)
Height (Width): 100 mm (3.94 inches)
Thickness (Base): 40 mm (1.57 inches)
Thickness (Tip): 20 mm (0.79 inches)
Weight: 6.2 kg (Nominal) / 13.7 lbs
Insert: Galvanized steel core strap (25mm x 6mm)

Note: Always verify manufacturer drawings, as "620" may refer to length in millimeters for custom extrusions.

Mechanical properties

Density: ~7.1 g/cm³ (zinc)
Hardness: Soft (Brinell ~25–40 depending on alloy) — easily machined or cast shape
Tensile strength: Low compared with steels; not load-bearing — used only for electrochemical protection

10. How to Read a "Non-Standard" 620 Datasheet

Many Chinese and European manufacturers use "620" as a model number, not a dimension.

Example: "Type 620" could be 300mm long.
Critical step: Always look for the "Rated kg weight" on the datasheet. A true 620-size anode for hulls is between 6.0 and 6.5 kg. If it weighs 3kg, you are buying a half-weight knock-off.
