2. Galvanic anode - Wikipedia

   en.wikipedia.org/wiki/Galvanic_anode

   An aluminum-zinc-tin alloy called KA90 is commonly used in marine and water heater applications. [9] Zinc and aluminium are generally used in salt water, where the resistivity is generally lower and magnesium dissolves relatively quickly by reaction with water under hydrogen evolution (self-corrosion).

3. Cathodic protection - Wikipedia

   en.wikipedia.org/wiki/Cathodic_protection

   Over time the galvanic anode continues to corrode, consuming the anode material until eventually it must be replaced. Galvanic or sacrificial anodes are made in various shapes and sizes using alloys of zinc, magnesium, and aluminum. ASTM International publishes standards on the composition and manufacturing of galvanic anodes. [10] [11] [12]

4. Aluminium–magnesium alloys - Wikipedia

   en.wikipedia.org/wiki/Aluminium–magnesium_alloys

   Aluminium–magnesium alloys (AlMg) – standardised in the 5000 series – are aluminium alloys that are mainly made of aluminium and contain magnesium as the main alloy element. Most standardised alloys also contain small additives of manganese (AlMg(Mn)). Pure AlMg alloys and the AlMg(Mn) alloys belong to the medium-strength, natural (not ...

6. Galvanic corrosion - Wikipedia

   en.wikipedia.org/wiki/Galvanic_corrosion

   Alloys of metals commonly used for sacrificial anodes include zinc, magnesium, and aluminium. This approach is commonplace in water heaters and many buried or immersed metallic structures. Cathodic protection can also be applied by connecting a direct current (DC) electrical power supply to oppose the corrosive galvanic current.

7. Aluminium–magnesium–silicon alloys - Wikipedia

   en.wikipedia.org/wiki/Aluminium–magnesium...

   The content of magnesium is greater than that of silicon, otherwise they belong to the aluminum–silicon–magnesium alloys (AlSiMg). AlMgSi is one of the hardenable aluminum alloys, i.e. those that can become firmer and harder through heat treatment. This curing is largely based on the excretion of magnesium silicide (Mg 2 Si). The AlMgSi ...
