Why Its Important To Take Care Of Magnesium Reels

[coastalobsession]

Question: Why is it important to take care of magnesium frame reels???

Answer: Magnesium frame reels are extremely light but yet they are not very salt tolerant. They in fact corrode extremely fast. I recommend cleaning your reel after every 2 outings....Heck make that after every outing! Also make sure the grease and oil you are using has anti-corrosion properties in it. (like Yamaha Marine Grease) 
Spraying your reel down with fresh water is a extreme no no with Mg reels. In fact all it does is spray salt back into the reel causing corrosion. I personally recommend (especially on Mg reels) wiping your reel off with simple green or salt away. These two agents will help keep your reel in great condition for years to come.

Here is a case of corrosion in a Chronarch 50mg

Ouch! Guess this reel is gone.
Sorry for your loss.

It wasnt mine. It was a clients.

I've seen and worked on Calais used in the brackish delta waters and they look like that Chronarch.

I have used a Antares AR/Calais 100A in the salt chasing Barramundi for over 6 years and it is fine...

You're either lucky or you've rinsed it off enough to rid it of salt.

Galvanic Corrosion

    Noble metals are those that are chemically inert when it comes to oxygen: they don't rust. Most metals have a certain degree of nobility, from graphite and platinum on the "most noble" end of the scale to magnesium and zinc on the "least noble" end of a list of metals called the "Galvanic Series." When two dissimilar metals, like bronze and aluminum, are in close proximity to each other in an electrolyte, like saltwater, a weak wet cell battery is formed. An electrical current flows from the less noble metal, the aluminum boat hull, to the more noble metal, like a stainless steel propeller shaft or an outboard motor's steel lower unit. This flow corrodes the less noble metal.

Zinc, Magnesium & Aluminum are used to prevent Corrosion of other metals on boats & motors etc..
Magnesium will Corrode fast Depending on the metals its close to...
In Saltwater it goes very fast!!!!   

Zinc & Magnesium are used as Attractants on Boats to corrode and save the More noble metals.

Anodes   (small sections/plates of Zinc or Magnesium) are fastened to boat engines and hulls to attract the corrosion & Save the other metals..    They are used in Bridges and many other structures that are in water also...    Replaceable Anodes !!   Save the Metal...   

Make sure your Reels are fully protected!!! !

Frank:  Kudos.  Good explanation of metal corrosion.  Less noble and more noble metals are new expressions to me, but just the terminology goes a long way to understanding the dynamics of corrosion and placing sacrificial anodes on boats and engines.  Dominick

Can you point me to the source which says that the frame for the Calais 100A is made of magnesium? The Shimano Japan website indicates that the Antares AR (same reel as the 100A) is OK for saltwater  use. http://fishing.shimano.co.jp/product/reel/268

Moreover, from the tacklewarehouse site we get the description:

".... Solid, unflexing one-piece Aluminum frame. Aluminum sideplates keep moving parts in precise alignment..."

Calais reels are used widely in Oz for chasing Barramundi etc in the salt and generally have an excellent reputation for durability and performance.

So much for Shimano's proprietary clear coating made to protect the mag. from the effects of saltwater.
