FOR ALUMINIUM

Anodized Finishes – (2, 3a, 3b, 3c, 4a and 4b): Anodized finishes are intended to provide corrosion resistance, improve paint adhesion and abrasion resistance, for aluminum and aluminum alloy parts. Good dielectric properties

Anodized (Hard) Finishes – (5): Color will vary from light tan to black depending on alloy and thickness. Provides very hard ceramic type coating. Good dielectric properties. Corrosion resistance is good.

Caution-(5):
Anodized finishes are recommended on aluminum alloys of 1/2″ in diameter or greater due to the higher current required to apply said coating.


Silver Plated Finish-(10):
Use on aluminum to enhance conductivity.


Alodine–(13):
Provides protection and corrosion resistance. For aluminum and aluminum alloys.


Iridite–(22):
Primarily used for protection against corrosion where lower electrical resistance is required. Will improve adhesion of paint systems on aluminum and aluminum alloys.


Lubricant – Solid Film – Heat Cured – Corrosion inhibiting (34a, 34b):
Reduces wear and prevents galling when used on aluminum and aluminum alloys.
