![]() ![]() IF YOU ORDER MIL SPEC MEDIA WE CANNOT SEND IT WITH AMS CERTIFICATION AND VICE VERSA. To be clear, all AMS beads will meet both Mil Spec (a lower quality, larger distribution bead) as well as the Aerospace Material Spec. COA's are available for either Mil Spec, or AMS, but not both (simply because they are different stock numbers). An AMS spec bead is generally used for shot peening and a Mil spec bead is generally used for shot blasting. This is why AMS is slightly more expensive. (Note: The minimum % of rounded beads will differ from size to size: 65% to 90% depending on size of bead). The AMS Spec beads are a slightly tighter size range than mil spec, and have more round beads, yet are the same chemical composition of glass beads. The table below details Mil-Spec Sizing Parameters. We will ship MIL SPEC, NON-AMS media unless you specify this by selecting the appropriate specification from the drop down menu. 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.Īvailable in either MIL-PRF-9954D, or AMS (Aerospace Material Spec). pressure), as well as wet and dry blasting operations. ![]() These glass beads are suitable for suction (80 psi max. 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. 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. However, there are hundreds, if not thousands of different applications using glass beads. 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. (Try plastic beads if you need something even more gentle.) 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. 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. ![]()
