The Science Behind AL-COAT
How it Works
Capable for use across a wide range of industries, AL-COAT ensures premium protection for aluminum alloys through its advanced technology. In fact, implementing AL-COAT as a surface treatment solution provides performance similar to stainless steel.
AL-COAT differentiates itself from similar coatings by providing a high-chromium alloy that is also both dense and non-magnetic. The coating is also uniform in both its appearance and deposit thickness, which ranges from .000050” to .001” (1.27 µm to 25.4 µm).
Once applied, AL-COAT ensures long-lasting protection and performance. Namely, the coating increases the wear resistance of an aluminum application while reducing surface friction and preventing galling. AL-COAT’s adherence and ductility also ensures longevity in even the most harsh and corrosive environments, leading to significantly less wear and tear over a longer period of time.
