Performance Metals HC5A Aluminum Hull Anode with Red Spot Wear Indicator

The Performance Metals HC5A is a premium Navalloy® aluminum hull anode manufactured to military specification MIL-DTL 24779, designed for superior corrosion protection in all water types—salt, brackish, and fresh water environments. This bolt-on hull anode replaces ZHC-5 and provides reliable sacrificial protection for your vessel's underwater metal components.

Key Features:

• Includes exclusive, patented "red spot" wear indicator for easy visual monitoring of anode life
• Manufactured to military specification MIL-DTL 24779 ensuring consistent quality and performance
• Navalloy alloy contains approximately 5% zinc and trace Indium to prevent oxide layer buildup
• Aluminum alloy provides more protection and lasts longer than zinc anodes
• Made in USA

This sacrificial anode protects your hull, propeller, shaft, and other underwater metals from galvanic corrosion by becoming the least noble metal in the system. Weighing 1.9 lbs, this anode provides protection equivalent to a 5.7 lb zinc anode, making it an efficient choice for vessel protection. The patented red spot indicator turns visible when the anode has depleted to replacement level, taking the guesswork out of maintenance schedules.
