Aluminum is one of the most versatile metals used in the industrial and manufacturing industries today. Aluminum is lightweight yet highly durable. These qualities make aluminum the perfect choice for the fabrication of a wide range of consumer items.
The final phase in the fabrication process for many aluminum components is polishing. Polishing may appear to be pretty straightforward, but there are some tips and tricks that can be used to improve the effectiveness of any aluminum polishing process.
1. Avoid Polishing in the Sunlight
Doing something as simple as completing the polishing process indoors can significantly improve the quality of your aluminum polishing.
The heat radiating from the sun has the potential to harden the polishing medium you are using to shine up your aluminum components. This will reduce the luster of the metal once polishing is complete.
The sun can also cause the aluminum to overheat during polishing, potentially altering the dimensions of the component and compromising its integrity. Keep all polishing activities indoors where you can control the temperature to avoid any problems with achieving your desired aesthetic.
2. Be Prepared to Use Acid Washing
Acid washing can be a valuable part of the polishing process. Aluminum is a porous material, which means that it can absorb some of the chemicals, solvents, and other contaminants it comes into contact with during fabrication.
You may discover that the surface of your aluminum appears to have milky gray spots even after you have engaged in multiple rounds of polishing. Acid washing can get rid of these milky discolorations.
A small amount of phosphorous acid can be placed directly on the affected areas. Once the acid forms a milky white coating over the stained area, traditional polishing techniques can be used to remove both the acid and the discoloration from your aluminum.
3. Keep Polishing Equipment Clean
Cleanliness is critical to the success of your aluminum polishing activities. Even a single particle contaminating your polishing buffer or the surface of your aluminum can cause a tremendous amount of damage.
The contaminant particle will create grooves and scratches in the surface of the aluminum, marring the smooth surface and preventing a uniform shine.
You should clean the area you intend to polish right before polishing begins to remove any dirt or debris. Always use tools that have been cleaned and wiped down with a lint-free cloth.
Keep your tools on a moving cart to avoid having them come into contact with contaminants on your work table or floor. Attention to cleanliness will significantly enhance the results of your aluminum polishing.
