Advantages of Aluminium Anodes

Voltage:            Aluminium anodes generate a lower voltage (-1.1V) than Zinc (-1.03V) providing increased protection.

Longer Life:       Aluminium anodes will last between 30% and 50% longer than zinc. The Ampere Hour Capacity (AHC) per pound-weight of aluminium alloy is 1150 AHC compared to 368 for zinc.

Lighter:             Aluminium alloy is two and a half times lighter than zinc.

Eco-Friendly:     Aluminium alloy does not pollute.

Red Spot:          Patented Red Spot wear indicator appears when 50% of the anode is wasted

Re-Immersion:   Aluminium alloy works immediately on re-immersion because the aluminium hydroxide is porous. Zinc hydroxide is impermeable and must be burnished off before the zinc anode is effective.

Waters:             Aluminium alloy is equally effective in fresh, brackish and salt water.

Boat:                Aluminium anodes can be used on any type of hull material – fibre glass, aluminium or steel, without fear of overprotectin
