Description

Description Aluminum anodes have long been used in the fight against corrosion. The Farwest line Pier and Piling anodes are designed for use on offshore structures such as piers, pilings or other structural support steel in need of sacrificial cathodic protection. The cast-in anode core is either welded, bolted, or clamped to the structure that is to be protected to ensure a reliable, low resistance connection. ALOLINE aluminum anodes are designed for optimum performance under a variety of environmental conditions and temperature ranges. Cast in different sizes and weights, ALOLINE anodes provide maximum performance in seawater and brackish environments.Typical Chemical Composition Element Percentage Indium (In) Zinc (Zn) Silicon (Si) Copper (Cu) Iron (Fe) Cadmium (Cd) Others, each Others, total Aluminum 0.016 to 0.02% 4.75 to 5.75% 0.08 to 0.12% 0.003% Maximum 0.12% Maximum 0.002% Maximum 0.02% Maximum 0.05% Maximum Remainder Performance Characteristics Anode Capacity Potential (Calomel) Consumption Rate 1150 amp hours per pound (Minimum) 1.080 volts (Minimum) 7.6 pounds per amp year Available Sizes Aluminum anodes are available in many different shapes, weights, and core configurations. While many of these configurations are listed in the following charts, many more anodes are available but not shown.
