Glass bead blasting will NOT damage your substrate (but will leave an anchor profile), and works best on softer metals such as brass, aluminum, plastic, die-cast surfaces.  Glass bead blast abrasives media comes in different sizes just like other abrasives do, but they generally use a different sizing chart, please see the chart below.  The main purpose for shot blasting with glass bead media is to create a compressive stress pattern and the elimination of microscopic defects in the surface of your part.  However, there are hundreds, if not thousands of different applications using glass beads.

Glass beads contain NO FREE SILICA.  Glass bead blasting will not leach toxins into the environment, will not leave residue on work pieces, will not cause dimensional changes to the base part being cleaned.  Bead blasting will leave even and spherical impressions on the pieces being cleaned, and will create and anchor profile for new paint to adhere to.  These glass beads are suitable for suction (80 psi max. pressure), pressure pot (40 psi max. pressure), as well as wet and dry blasting operations.  They are made from hardened soda lime glass, and is available in all standard sizes, and have a low breakdown rate, lower disposal, and lower maintenance costs vs other cleaning methods such as harsh chemical treatments.

Available in either Mil-Spec or Non Mil-Spec, or AMS (Aerospace Material Spec).  We will ship NON-MIL, NON-AMS media unless you specify this by selecting the appropriate specification from the drop down menu.   The table below details Mil-Spec Sizing Parameters.  Non mil-spec media is a bit more relaxed, having a slightly larger distribution spread and may contain beads that have cracks or blemishes.   The AMS Spec beads are a slightly tighter size range than mil spec, but they are the same chemical composition of glass beads (this is why they are slightly more expensive).  An AMS spec bead is generally used for shot peening and a Mil spec bead is generally used for shot blasting.  COA's are available for either Mil Spec, or AMS, but not both (simply because they are different stock numbers).  When you place your order, if you need a Mil Spec COA, then order Mil Spec media.  If you need a COA for AMS, then order the AMS beads.  To be clear, all AMS beads will meet both Mil Spec (a lower quality, larger distribution bead) as well as the Aerospace Material Spec.
