Magnesium rods are made from magnesium alloy. They are used for various applications, including motor housings, pressure vessels, and aerospace applications. There are two kinds of magnesium rods: casting and extrusion.

Cast magnesium anode rods are usually made with a specially-shaped steel core. This core provides the anode with good low-resistance when current flows through it.

Extruded magnesium rods are designed for compact installation. They have to pass special installation requirements.

When a new magnesium rod is being installed, it must be welded to the iron mounting nut. The nut is a key component in the whole installation process. If the nut becomes corroded, the entire magnesium rod will be ruined.

Several companies make magnesium rods. Boeing is an award-winning supplier. DOAN is a quality brand from the United States.

Magnesium rods should be replaced every 2 years. If the water quality is poor, they should be replaced sooner.

It is recommended to replace the anode rod when the weight decreases by more than 75%. However, replacement depends on the usage of the anode. You should use a socket and breaker lever to remove it.

Some countries impose strict rules for the corrosion products that are used to protect the magnesium alloy. These products must meet national and international standards.

Before purchasing a magnesium bar, you should test it first. Many cheap magnesium bars are of inferior quality. Also, you should learn to use it properly.

Magnesium rods are available in a wide variety of shapes, sizes, and specifications. They are available in phosphor bronze, copper, and magnesium.
