Electrophoretic Aluminium Profile | Electrophoretic Technolog
Aluminium's ability to respond to Electrophoretic makes it an important metal. The fact that Aluminium can be made in attractive finish
makes it adaptable to a wide range of applications from partitions to vehicle components. Anodising is a conversion of the metal,
which creates a protective inert film of Aluminium oxide. This film will not crack, peel, or chip unless subject to severe stress or extreme
thermal changes.
The Electrophoretic sprocess is Electro-chemical in which the natural oxide film is created by passing an electric current through dilute
Sulphuric ,Aid with the Aluminium part as the anode. The electrophoretic film created is microscopically porous, which needs "sealing" in
a simple soap addition or some of the newer seal additives.
The full process usually involves a chemical pre-clean, followed by immersing the products in a chemical to give the required finish. Phosp-
horic Acid solutions giving a bright finish and a caustic soda based solution, giving a matt appearance.
Bended,Stamped,CNC Processing
Electrophoretic also provides a means of colouring the oxidised metal. Anodic films are coloured by a variety of methods. Pigments and
inorganic dyes are dissolved in heated water and the products immersed prior to sealing while they are still porous. The colour is sealed

in place by the usual method. The more durable coloured films necessary in exposed environments can be produced as part of the anodic la-
yer and are quite permanent.
The thickness of the Aluminium Electrophoretic coating can be varied by processing time. The following figures are usual.
Suitable for internal applications, and outdoor applications where cleaning is very frequent, for example, caravan trim.
15 Micron
Recommended for the majority of ordinary architectural requirements.
25 Micron plus is achieved by Hard Anodising this is done by varying the electrolyte composition and modulating the process parameters.
Hard anodic films are used to provide abrasion resistant surfaces on bearings, pistons, gears, and other components.
