Propeller anode zinc alloy is a sacrificial component used to prevent corrosion in marine environments. It corrodes preferentially, protecting the propeller and other metal parts from galvanic corrosion. Regular inspection and replacement ensure effective corrosion control.

Size: Typically ranges from 5 kg to 50 kg, depending on application.

Grade: ASTM B418 Type I or Type II, MIL-A-18001H.

Viscosity: Not applicable (solid alloy).

Buoyancy: Negligible (used as sacrificial anode, not for flotation).

Material: High-purity zinc alloy (Zn-Al-Cd or Zn-Al).

Corrosion Protection: Sacrificial anode for cathodic protection in seawater.

Shape: Customized to fit propeller shafts or hulls.

Operating Environment: Marine/offshore applications.

Electrochemical Capacity: ~780-820 Ah/kg.

Potential: -1.05V to -1.10V vs. Ag/AgCl reference.
