Aluminum Flakes

With aluminum flakes, it’s all about the high surface to weight ratio. With a thickness of 25 microns and length and width dimensions 600 or 1000 × 1000 microns chemical reactions are more predictable.

Aluminum flakes are safer than aluminum powders. They are rated as non-hazardous to handle. See the “Shape Makes A Difference” article. That’s where Transmet’s Aluminum Flakes are a game changer. With Transmet, you can ensure that each aluminum flake comes in the correct dimensions to provide stability for every project.

With a platelet-like shape, these aluminum flakes are sturdy despite being the same thickness as aluminum foil. Transform your chemical process with our industry-best Aluminum Flakes.

How We Produce Aluminum Flakes

Producing aluminum flakes is a delicate process. At Transmet, we have tons of experience doing this successfully. We have produced north of 50,000,000 pounds of rapidly solidified products making us the pre-eminent producer in the world. We also produce other aluminum alloys upon request.

Applications for Aluminum Flake

Feedstock for chemical reactions

Transmet’s Aluminum Flakes make for excellent feedstock to support large-scale chemical reactions.

Fuel cells and batteries

Aluminum flakes are also used as the cathode in fuel cells and batteries. Aluminum has become a catalyst in recent years for the creation of hydrogen fuel.

Exothermic applications

Releasing energy in the form of heat into the atmosphere oftentimes comes with the help of aluminum flakes, which are known to provide excellent volumetric exothermic enthalpy.

Binder agent for master alloy briquetting

Aluminum flakes can be a desirable binding agent for many applications, including for master alloy briquetting.

Drain cleaners

Aluminum is a prime ingredient in most drain cleaners. It reacts with sodium hydroxide to generate hydrogen gas bubbles that help homeowners break up clogs.

Thermal and electrical conductivity enhancement in plastics

Thanks to aluminum’s ability to transfer a high amount of heat, it is used as an enhancement element in plastics.

Granular alternative for highly reflective roofing applications

Aluminum flakes serve as a durable and highly reflective substance for roofing applications. Roofing granules help roofing manufacturers improve reflectivity on their projects.

Aluminum Flakes Product Specifications

Transmet’s aluminum flakes come in two varieties or shapes: rectangular (K-101) flakes and square (K-102) flakes. Although they have a similar thickness, the square flakes are nearly twice as long and come in a larger standard package size.
