Magnesium firestarters are a great tool to have in your survival kit. They are extremely lightweight and give off a large amount of sparks to start a fire when used with dry tinder. They are an old concept that has been revitalized by new generations of campers. However, many people may be unsure of how to use them and if they will work for their specific needs. This article will help to answer any questions that you may have about magnesium rods.
What are the different types of magnesium rods?
There are two main kinds of magnesium anode rods: cast and extruded. The cast magnesium anode has a steel core that is generally half or two-thirds the length of the rod. The core is inserted into the casting before it is poured. The cast magnesium rod then has an iron mounting nut welded to it. The steel core provides an electric current that causes the magnesium to be consumed while the metal liner is protected from corrosion.
The extruded magnesium anode is made from a thicker alloy, typically AZ63 or AZ31. This makes it more durable than the cast magnesium anode, which can be easily damaged by vibration or shock. This type of anode also has a hollow center, so it can be rolled to form a thinner rod with a larger surface area. The hollow center can also hold a gas generator to provide an electrical charge for the anode.
