Aluminum Flakes

Can Transmet aluminum flake replace aluminum powder?

Yes, our flakes can replace powder. Our flakes have the surface area of fine powder yet are much safer due to the mass of each flake. We have several companies who replaced aluminum powder with our flake and reported faster reaction time and a safer work environment.

What are the benefits of aluminum flake over aluminum powder?

Flake benefits include safe handling and usage and a very uniform shape. In a chemical process flake dissolves as a flat sheet; meaning the surface area stays constant while dissolving unlike a powder that is more spherical so as it dissolves the surface area decreases and the reaction rate slows.

Can aluminum flake be added to thermoplastics?

Yes. Transmet flakes are used in plastics for EMI/RFI shielding and to enhance thermal conductivity of many plastic compounds. The thinner flakes mean fewer pounds are required to get the needed results.

Can aluminum flake be used for reflective roofing?

Yes. Transmet aluminum flakes are used in cool roofing programs. In many cases the flakes are applied to the top of the roof and adhered by the asphalt. The reflectivity of the flake protects the roof from ultraviolet rays and keeps the roof cooler thus saving energy. Aluminum flake can increase the reflectivity of a roof surface to about 80%.

Will aluminum flake ‘float’ in certain media?

Yes. Transmet flake will float. This is not only due to the bulk density of the flake but also the buoyancy of each flake along with the wetting properties.

Is aluminum flake hazardous?

Aluminum flakes are safe when properly handled. While the surface area is as high as powder, the mass of each flake makes it much safer.

Is aluminum flake known by different names?

Yes. Transmet aluminum flakes are also known as aluminum chips, granular aluminum, high surface aluminum particles and aluminum particulates.

Can Transmet aluminum flakes be made in different sizes and thicknesses?

Yes. There are too many possibilities to list. Please contact Transmet to discuss with one of our experts.

Zinc Flake

What are the benefits of zinc flake over zinc powder?

Zinc flake has a higher surface area pound for pound. Zinc flake also has less of an oxide layer on the surface and its shape is very uniform.

What are some of the processes zinc flake has been used in?

Zinc flake typically has been used in alkaline batteries, fuel cells and chemical process needing zinc to react. There are too many possibilities to list. Please call Transmet if you have a question about zinc flake in a specific process.

Is zinc flake hazardous or have any special handling needs?

Zinc flake is safe when handled properly. The most critical issue is to keep the zinc flake dry.

Is zinc flake known by any other names?

Zinc flake is also known as zinc powder, granular zinc, zinc particulates and anode zinc.

Aluminum Shot

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?

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 that 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.

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.

Zinc Shot

What is the benefit of Transmet zinc shot over other media?

Cast shot outlasts all other zinc media. From a metallurgical view zinc softens as it is used until it fails. Cut wire is drawn then chopped, so it is partially worn out in the forming process. Transmet can also customize the alloy specifically to enhance the shot performance.

What is the difference between cast zinc shot and other zinc shot?

Cast zinc shot is produced by melting zinc ingot and centrifugally atomizing the molten steam to form the shot. In producing zinc cut wire the ingot is drawn into wire and then the wire is cut to size.
