Al-TransTM, Al based composite

Al-TransTM is a family of aluminum composite 2-phase coatings developed for a broad range of applications.  The above micrograph is of an Al-TransTM that was developed as a replacement for zinc chromate for use as a grounding strip on steel telecommunications racks.  It has met the following specifications:

  • Adhesion strength: ASTM C633, 10ksi (epoxy failure)
  • Adhesion to substrate: passes ASTM B571
  • Paint adhesion to coating: ASTM D2794, 120ft-lb
  • Corrosion: ASTM B117, 5,000hrs (no rust formation)

 

Other Al-TransTM coatings are being evaluated and qualified for cadmium (Cd) replacement, field repair of IVD coatings, AlClad repair and replacement, and chromic acid anodized replacement.
