What are the main differences between zinc, magnesium, and aluminum anodes in the Tecnoseal range for boat protection?
In the Tecnoseal range, zinc, magnesium, and aluminum anodes serve different purposes based on water type. Zinc anodes are best Boat Anodes For Saltwater, while magnesium is ideal for freshwater use, offering more active protection. Aluminum anodes, being more versatile, can be used in both salt and brackish water, providing longer-lasting protection. Tecnoseal, one of the leading suppliers of sacrificial anodes, manufactures a wide range of these anodes to cater to various boat types and environments.
How do stern anodes differ from outboard anodes in the Tecnoseal range?
Stern anodes in the Tecnoseal range are designed to protect the metal components of the stern area, such as the stern drive, from corrosion, while outboard anodes are specifically engineered to safeguard the outboard engine parts, like the propeller and lower unit. Both types of anodes act as sacrificial anodes for cathodic protection, with Tecnoseal offering a wide range to fit various brands to ensure long-term protection in the leisure boat market.
