How to guide: Cleaning metals for repair part 1 aluminum repair with Alumaloy

May 4, 2011

Cleaning before using any of our products is very important.  I plan to do a three part how to guide explaining what is needed to be done for all three of our metal repairing products.  In some cases it may just need to be wiped with a cloth.  However, in most cases, it will require an abrasive or mechanical cleaning. This usually can be accomplished with the use of a wire brush or sandpaper.  Cleaning is very important particularly with How to guide: cleaning metals for repair part 2 cast iron repair with Castaloy and How to guide: cleaning metals for repair part 3 stainless steel repair with Steelaloy because it reduces the chances of future corrosion and helps make a more solid melding.  In this article I would like to talk about Alumaloy, a product used to repair aluminum.  More information can be found here about the physical properties of Alumaloy.

Aluminum is generally one of the easiest metals to work with as it is the easiest to clean. However,  be careful to take all of the precautionary measures to ensure a great outcome.  Areas to be mended will need to be completely free of paint, dirt, oil and other debris before using our aluminum repair rod. Any contamination can cause poor wetting and will eventually weaken the join points.  A smooth break may only need a quick wipe with a clean cloth or rag.  Be sure any liquid is removed in this step.   A small wire brush or sandpaper will usually be enough to remove particles and matter from a rough piece. If your project requires a more aggressive cleaning, you may want to use a wire wheel on a drill. Make sure to wipe it down afterward to remove any loose grit or debris. Also, you will want to keep in mind that it is important to maintain the proper surface roughness as wetting on a rough surface occurs much more readily than on a smooth surface of the same geometry. If there is any oil on the metal, you may need to use a cleanser to remove it.  Be sure the area is completely dry after use or thoroughly wiped down to avoid fumes and fire hazards. Be thorough so that when you begin the repair process, you do not have to stop once the metal has been heated and you have begun your repair.

Part 1:  How to guide, cleaning focuses on Alumaloy to repair aluminum.
Part 2:  How to guide, cleaning focuses on Castaloy  to repair cast iron.
Part 3:  How to guide, cleaning focuses on Steelaloy to repair stainless steel.

We hope these cleaning guidelines have been helpful to you in the use of our products. If you have questions or comments please feel free to visit our aluminum repair forum or post your comments directory to this article.  Feedback always helps us to serve our customers better.
