Zinc Anode 620 Datasheet Extra Quality Direct
-1.05 Volts (relative to Ag/AgCl reference electrode).
The "620" designation typically references the nominal weight or dimensional classification within standard manufacturing catalogs (often correlating to a nominal 20-pound class or specific dimensions depending on the manufacturer). Below are the standard physical attributes for a weld-on or bolt-on 620 series hull anode. Physical Dimensions (Standard Configuration) 305 mm (12.0 inches) Width: 152 mm (6.0 inches) Thickness: 32 mm (1.25 inches) Gross Weight: 10.4 kg (23.0 lbs) Net Zinc Weight: 9.1 kg (20.0 lbs) Insert Types
The is a high-solids, two-pack epoxy zinc-rich primer designed for superior corrosion protection of steel in aggressive environments. It acts as a sacrificial layer, providing "galvanic protection" to the steel substrate. Product Overview zinc anode 620 datasheet
Execute a continuous 6 mm fillet weld on both sides of the core tabs.
: These sacrificial anodes often feature an "iron foot" (the internal steel strap used for welding) with a length of Composition : These anodes typically follow standards like MIL-DTL-18001L or ASTM B418, using 99.99% pure zinc. Performance Data : Approximately 780 Ah/kg. Consumption Rate : Roughly 11.2 kg/A-year. : -1.030 mV relative to Ag/AgCl in seawater.

The 620 zinc anode conforms to the specification (also known as ASTM B418 Type I). This formulation uses high-purity zinc alloyed with controlled amounts of aluminum and cadmium. These additives prevent the formation of an isolating passive layer. Chemical Composition Limits Zinc (Zn): Remainder (Minimum 99.31%) Aluminum (Al): 0.10% – 0.50% Cadmium (Cd): 0.025% – 0.07% Iron (Fe): 0.005% Maximum Lead (Pb): 0.006% Maximum Copper (Cu): 0.005% Maximum
Small anodes to protect engine parts. Infrastructure & Industrial Applications : These sacrificial anodes often feature an "iron
Zinc anodes operate by maintaining a lower electrical potential than the steel structure they protect. Electrochemical Characteristics
Minimum 6 - 8 hours; Maximum (Dependent on the specific topcoat, ensure surface is free of zinc salts before overcoating). 4. Surface Preparation Guidelines
Replace the 620 anode when it wastes down to .
Generally restricted to stripe coats, small repairs, or areas inaccessible to spray equipment. Proper film thickness is harder to achieve with brushes. 6. Health, Safety, and Storage Zincanode 620
