Cast Aluminum Shot
The Transmet Cast Aluminum Shot provides the delicate touch needed to keep your gasket surfaces safe while simultaneously removing corrosion.
From cleaning unwanted rust to flash removal of light metal castings, this cast aluminum shot serves a number of purposes. This lightweight blast media excels in coating removal, paint removal, and any cleaning application that requires a gentle touch. Cast aluminum shot is a good choice when a non-contaminating blast media is needed on aluminum parts.
Transmet manufactures cast aluminum shot in 2 alloys. 319, the harder of the two is a good choice for general blast cleaning. Our 2N is dead soft aluminum great for cleaning softer surfaces that can’t be profiled. 2N is also a good choice for other non-blasting applications.
Cast Aluminum Shot vs The Rest
The Transmet Cast Aluminum Shot is built to produce less dust than other blast media, outlasting many of the other cast shots on the market. And when you compare Transmet’s Cast Aluminum Shot to glass bead or plastic media? It’s not even a fair fight—our aluminum shot outlasts both by over one thousand times while effectively cleaning your parts!

Main Benefits of Cast Aluminum Shots
TWO ALLOYS OF CAST ALUMINUM SHOT
The 319 alloy is the most popular and aggressive form of Transmet Cast Aluminum Shot. It was engineered to have an ideal blend of hardness and durability with an average cycle life of 8,000 cycles. The 2N alloy is made from very pure aluminum and is significantly softer than the 319 alloy and not as aggressive. It is used on very delicate surfaces where a very smooth finish is desired. Average cycle life is 14,000 cycles.
