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!

Applications for Cast Aluminum Shot

Key role in chemical manufacturing

Cast aluminum shot has a huge energy potential. Examples are fuel cells, batteries, and fuel for refining metals like titanium.

Removing paint and e-coat

Transmet’s Cast Aluminum Shot can easily remove powder coat, e-coat and more without risking leaving any signs of visible wear.

Additive in cast tooling

Aluminum shots help boost thermal conductivity for cast epoxy tooling reducing cycle times and reducing warping as the parts set. Aluminum shot is also less expensive than epoxy resin so it will keep tooling cost low.

Surface finishing non-ferrous components

Non-ferrous metals like aluminum magnesium, and zinc need to be surfaced without getting damaged. This enables them to retain their integrity for industrial applications without galvanic corrosion.

Removing ceramic from investment castings

Getting ceramic out of investment castings is a delicate job. Thankfully, Transmet’s Cast Aluminum Shots are made to be gentle. Removal of ceramic shell molds has never been simpler and hassle-free.

Purpose of Cast Aluminum Shots

With the help of Transmet’s Cast Aluminum Shots, you can increase the lifespan of your equipment while providing a smooth, bright finish that doesn’t include any nasty corrosion or contamination. The aluminum shot sends less energy to the parts being blasted and helps prevent warping. It’s the perfect lightweight substance for surface preparation. The low bulk density and hardness cleans without damage to delicate surfaces.

Eliminating Shot Blasting Machine Wear

Shot blasting machines go through a lot. With Transmet’s Cast Aluminum Shot, you will greatly reduce signs of damage and wear on your most critical internal components like the control cage, wheel liners, and blades. Similar to our Cast Zinc Shot, the Cast Aluminum Shot can handle many thousands of hours of blasting without noticeable damage.

Main Benefits of Cast Aluminum Shots

With the ability to avoid corrosion as well as high thermal conductivity, aluminum cast shots are renowned for their durability and versatility in many applications. Discover how Transmet’s Cast Aluminum Shot will enhance your process.

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.
