Performance Metals is a Pennsylvania based manufacturer of premium aluminum sacrificial anodes. We use a special alloy made to the military specification MIL-A-24779, which details the exact percentage content by element. The alloy used is a blend of aluminum and zinc (5%) with a trace of indium. This mixture gives a better protection voltage and ensures that the anode stays clean and corrodes evenly. Performance Metals is the only supplier of the wear indicator.- Superior Aluminum/Indium alloy for increased protection
- Exclusive “Patent Pending" Wear Indicator is embedded in the anode and appears in the surface of the anode when it wears to half its original size.
- Unique attractive packaging
- 2-1/2 times lighter than zinc
- Installation instructions included
- Better Protection: Aluminum is more active than zinc providing a greater potential difference for cathodic protection.
- Longer Life: An aluminum anode of the same size gives up to 50% additional life compared with zinc and 5 times compared with magnesium.
- Remains Active in Freshwater: Zinc anodes can form a coating in freshwater after a few months, which will stop them from working.
- Environmentally Friendly: Zinc alloy causes pollution, which is harmful to marine life. Aluminum is safe.
