Aluminum Vs Magnesium Anode Rod

Aluminum vs magnesium our review.

Aluminum vs magnesium anode rod.

Since the working mechanism is slow this is the reason why it produces low voltage during electrolysis. Anode rod magnesium or aluminum. Aluminum anode rods are cheaper than magnesium anode rods. Reaction with water elements can sometimes lead to production of hydrogen sulfide which comes out as a rotten egg smell in the water.

The chemical reaction for rusting begins by oxidation which is when iron loses two of its electrons to the oxygen found in the tank. Magnesium rods are more expensive. Unlike aluminum anode rods dissolved magnesium offers health benefits. Both magnesium and aluminum are less noble metals meaning they corrode quickly in water.

So you suspect your water heater s current anode rod needs replacing so you re figuring out which type you ought to purchase as a replacement. A magnesium rod will generally last less than an aluminum rod. Aluminum anodes tend to be cheaper than magnesium anode rods. One issue with aluminium rods is that the corrosive material that is formed on the anode tends to harden and sink to the bottom of the water tank.

The aluminum rods are the slowest performing anode rods built from aluminum. An aluminum water heater anode rod is placed into a water heater to prevent corrosion. To be fair this type of rod is much less expensive when you compare it with the magnesium or any other type of rods. This can potentially find its way into your taps and cause issues down the.

In the same way that ships use sacrificial rods to protect the metal of the hull an anode rod attracts the corrosion and keep the rust and corroding elements away from the water tank itself. Aluminum and magnesium rods. Water heater anode rods. Let s put on our chemistry hats and explore this a bit further.
