What is Marine Aluminum Anode?
Aluminum anode is a kind of sacrificial anode, also known as aluminum alloy sacrificial anode, aluminum sacrificial anode, aluminum block, etc. It is called a sacrificial anode because it corrodes itself, sacrificing itself and protecting more important metals or equipment. Aluminum anodes are one of the commonly used sacrificial anodes that can be applied to many types of industrial equipment to protect them from corrosion.
Overview
Principle
The principle of aluminium anode is by forming a dense oxide layer on the surface of aluminium material, which prevents further oxidation and corrosion of aluminium material. When the aluminium material is coated with zinc anode, the zinc undergoes an oxidation reaction which prevents the aluminium material from being oxidised. It also improves the corrosion resistance and electrical conductivity of the aluminium surface, thus protecting the stability of the aluminium material.
Application
Aluminium anodes are commonly used on ship hulls, water heaters, pipelines, storage tanks, and oil refineries.
The Benefits of Using Aluminium Anodes
1. aluminium anodes are more active than zinc or magnesium anodes;
2. unlike magnesium anodes, they do not spark in salt or brackish water;
3. aluminium anodes have a longer life span and are the only type of anode that can be used in any body of water (e.g. fresh, brackish or salt water).
