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.

Standard packaging for 319 and 2N aluminum products is 50 lb. bags.
What are the benefits of Transmet’s cast aluminum shot over other media?
Transmet aluminum shot is cast from molten metal. Transmet can alloy and control the size of the shot by the speed of the centrifugal atomization process.
Can Transmet’s Aluminum shot be used in chemical processes?
Yes! In a chemical process the high purity is often preferred. Transmet shot can be certified to your needs by buying ingot that meets your standards for our casting process.
Can Transmet customize an aluminum alloy for my particular process?
Yes. Transmet can cast alloys to your specific needs.
What is the difference in Transmet’s 319 cast aluminum shot and 2N aluminum shot?
The 319 cast aluminum shot is cast from 319 alloy while the 2N is cast from pure aluminum. The 319 shot is significantly harder and is typically used for abrasive cleaning applications. The 2N shot is softer and very pure aluminum so it is used in chemical and filler applications.
Will the ‘tails’ on Transmet’s aluminum shot be damaging to my parts?
No. The ‘tails’ are a product of our process. The soft metal rounds up in about 50 cycles. Even with 100% new cast shot you will not see an issue with the tails. As part of a working mix new shot is less than 1% part of any mix.
Why does Transmet’s cast aluminum shot last longer than other aluminum shot?
When melting aluminum we can alloy to get the metal the best quality possible. The centrifugal atomization rapidly solidifies the shot so the grain structure is also enhanced beyond anything else available.
Can Transmet’s aluminum shot be used as a filler?
Yes! As a filler in epoxy or composites. Our casting surface has roughness that allows strong bonding in your material. Our unique shape offers a high bulk density to maximize the aluminum cast shot performance. Transmet shot wets out very well in epoxy and resin systems.
Can I see the finish on my part before I order?
Yes! Transmet has air blast and tumble blast equipment in our lab. We encourage you to send us your parts so we can blast them here so you can see the finish possibilities under various conditions.
Can Transmet aluminum shot be recycled?
Yes. In most cases, the left-over particles can be recycled.
What other names is aluminum shot known by in the industry?
Aluminum shot can be called shot media, blast media, cut wire, grit, granular and blasting media to name a few.
Can cast aluminum shot replace other kinds of media?
Yes! Our cast aluminum shot is made out of pure aluminum and has a higher bulk density compared to granular aluminum. Transmet’s process provides the ability to alloy and cast directly to size which results in a tougher, longer lasting product compared to cut aluminum wire.
