Abstract
Grit blasting is known to have decided speed and cost advantages over other methods of surface preparation for painting on steel, but there have been some questions as to its suitability for cleaning a relatively soft metal like aluminum. An investigation was made, therefore, to determine if grit blasting resulted in a significant loss in the mechanical properties of common structural aluminum alloys. The evaluation included three grits, three structural alloys (5083, 6061 and 7075) and a range of grit blasting times. Test panels were grit blased under both laboratory and field conditions. It was concluded that when a fine grit is used, the common structural aluminum alloys can be cleaned safely using standard industrial grit blasting equipment and procedures.
