SULPHURIC
ANODISING
The
most widely used anodising process, it produces transparent coatings
of optimum corrosion resistance. The film produced gives a range of
thickness from 1 - 25 microns depending on alloy and/or application
requirements. "The Honey combe type structure as shown in "What is
anodising" page" enables organic/inorganic colour dyes to be absorbed
into the pores of the film, for either decorative or identification
purposes. The majority of Aluminium Alloys anodised by this process,
including the magnesium silicon alloys commonly used in architectural
structures, have a natural silver grey appearance. Alloys with high
concentrations of copper or silicone will produce darker shades of
grey.
APPLICATIONS
AND USES
Sulphuric anodising is the most versatile of all anodising
processes because of the excellent properties of the coating, namely
it's high corrosion resistance, decorative appearance and everyday
wearability in conjunction with the lightness and strength of today's
modern aluminium alloys. The uses of the process are too many to mention
but are used extensively in the following applications: Automotive,
electronic/computer, architectural building and fittings, domestic
appliances, furniture and medical equipment.
