Zinc Anode | 620 Datasheet _verified_
. 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
Poor (Zinc can form a "crust" of oxide that stops the current; use Magnesium instead). If you'd like, I can help you: zinc anode 620 datasheet
>95% (No hydrogen embrittlement risk for high-strength steel). . Unlike other metals
Don't wait until the anode is gone to replace it. According to the Barnacle King's Guide zinc provides a very steady
