Aluminum Flakes

Transmet's K-102 Aluminum FlakesTransmet’s aluminium flakes are rapidly solidified in Transmet’s proprietary melt spinning process. The flakes are very uniform in size and shape. Transmet’s flakes have a high surface area to mass ratio making flakes a safer alternative to working with explosive powders.  Our standard flake is 99.93% pure aluminum as cast. 

We also manufacture a 99.99% high purity aluminum flake and other aluminum alloys upon request.

Transmet’s standard K-102 aluminum flake will contain about 7,000,000 flakes per pound. Each flake will be about the same thickness as a sheet of thin aluminum foil.

Transmet has produced over 50,000,000-lbs of rapidly solidified products in our history. Our know-how and expertise is unmatched in the world.

Past applications for aluminum flake include:

  • Feedstock for chemical reactions
  • Fuel cells and batteries
  • Exothermic applications
  • Binder agent for master alloy briquetting
  • Drain cleaners
  • Thermal and electrical conductivity enhancement in plastics
  • Granular alternative for highly reflective roofing applications

Details on how aluminum flakes can benefit chemical reactions can be found in the article Shape Makes a Difference.

For more information about our flakes in high reflective roofing applications you may visit the Aluminum Associations article or the U.S. Department of Energy article or our Highly Reflective Roof Coating page.
