Caldwell Casting/Performance Metals

<h3>About Performance Metals / Caldwell Casting</h3><p>Performance Metals — operating under the manufacturing banner of <strong>Caldwell Casting Co.</strong> in Cambridge, Maryland — is one of North America's most respected names in sacrificial anode technology. Performance Metals Products, which manufactures Navalloy® sacrificial anodes, completed its transition of business operations to Caldwell Casting, based in Cambridge, MD. The result is a vertically integrated operation where every anode is conceived, cast, and assembled under one roof in the USA.</p><h3>A Legacy of Corrosion-Protection Innovation</h3><p>Performance Metals has established a reputation for developing innovative, high-quality products in the corrosion market and is a leading supplier of exclusively aluminum sacrificial anodes. Their flagship material is <strong>Navalloy®</strong>, a proprietary aluminum alloy that sets the standard for recreational and commercial marine protection. Navalloy® anodes are made to the military specification MIL-DTL-24779B(SH) and contain approximately 95% aluminum, 5% zinc, 0.02% indium, and less than 0.3% of other trace elements.</p><p>What truly distinguishes Performance Metals from the competition is a commitment to eliminating guesswork for boaters. Exclusive to Performance Metals, each Wear Indicator Anode has a colored plastic indicator embedded within it that appears on the surface when the anode wears to half its original size — boaters can simply inspect the anode for the dot to easily determine when to replace it. This patented <em>Red Dot</em> wear indicator has become an industry benchmark. Performance Metals' Premium Line of anodes was the winner of the MAATS Innovation Award in 2004.</p><h3>Why Navalloy® Outperforms Traditional Zinc</h3><p>The choice of anode material matters enormously for long-term hull and drivetrain protection. Navalloy® does not pollute — zinc is a toxic metal that pollutes the water. Navalloy® contains only about 5% zinc, while zinc anodes are 99.9% zinc. Environmental agencies have determined that zinc sacrificial anodes are a major cause of pollution in marinas, and in some cases zinc anodes are being banned. Beyond the environmental advantage, Navalloy® anodes are suitable for use in all water types: salt, brackish, and fresh. This versatility makes them an ideal one-solution-fits-all choice for boaters who move between different waterways.</p><h3>Experienced Engineering Behind Every Cast</h3><p>All anodes are cast and assembled on site in Maryland, USA.
