Many people call Sacrificial Anodes "Zincs" because Aluminum was not used for various reasons - cost primarily. Aluminum Anodes are lighter and generally lasts almost twice as long as Zinc Anodes. As the price of Zinc goes up, the cost per pound ratio makes Aluminum more cost effective as an Anode material.


Anodes (Zincs) are available with a variety of cores: Steel or Aluminum Weld-on straps; Steel or Aluminum Bolt-on inserts; Steel cable inserts; Stainless Steel Nuts or Bolts; or Threaded Rods.

All Aluminum and Zinc Anodes meet US military specifications MIL-A-18001 & MIL-A-24779 also covered by ASTM-B-418-73, Type 1. Only graphite ladles & crucibles used - ensuring low iron contamination.


Whether is it for fishing boats, ocean going vessels, or crab traps we can provide low cost cathodic corrosion protection with Anodes. Custom Anodes are our specialty so please contact us with your requirements.
