Alloy selection is very important for correct protection. Zinc is really helpful to be used in salt water (not really helpful for fresh water). Aluminum is designed to be used in salt or brackish water, and has better performance and longer-lasting protection than zinc. Magnesium is intended ONLY to be used in fresh water, and is the one alloy proven to offer protection in fresh water. Martyr brand marine anodes are a subsidiary of Canadian Metal (Pacific). The use of advanced alloys and casting Martyr brand sacrifical anodes have gained an international reputation of superior quality.
Top of the range Martyr anodes are pressure diecast and manufactured to strict quality standards through an ISO 9001 Quality Management System
Martyr anodes offer maximum protection by maintaining quality alloys, free from impurities like iron, which is able to compromise performance
Three alloys to be had – Use Zinc (Martyr I) for salt water, Aluminum (Martyr II) for brackish water, or Magnesium (Martyr III) in fresh water.
Use alternative anode alloys when changing water conditions
Provides low cost cathodic protection of ocean-going vessels, structures and equipment constructed of iron, steel, aluminum, magnesium, and other metals
