Aluminum Sacrificial Anodes: Will They Catch Up to Zinc?
In the world of sacrificial anodes, zinc has long been the preferred choice for protecting boats and marine equipment.
But, the fact is that aluminum anodes are becoming more popular.
Why Aluminum is Gaining Popularity:
Versatility – Unlike zinc, which is superb in saltwater, aluminum anodes perform well in saltwater, brackish water, and even freshwater.
This makes them a go-to choice in countries with numerous lakes, rivers, and mixed-water environments.
Lighter – Aluminum is significantly lighter than zinc, which can be advantageous in specific applications.
Despite its lightweight nature, aluminum offers satisfactory corrosion protection performance.
Longevity in Brackish and Freshwater – Aluminum anodes are more active than zinc and less complicated than magnesium.
They tend to last longer in brackish or freshwater conditions, making them an increasingly popular choice for inland and river vessels.
Market Trends:
Currently, aluminum accounts for less than 20% of our sacrificial anode sales.
However, the gap is slowly narrowing with rising demand, particularly in areas with varied water conditions.
Nautical Armor is steadily investing in aluminum anodes to meet this growing demand.
So, what has been your experience?
Do you stick with zinc, or have you switched to aluminum? Both are good!
