Anodized
Aluminum
Anodising is the electrically induced oxidation of
the surface of aluminium in an acidic solution. The anodised layer
is greatly increased in thickness over that of natural oxidation.
By controlling temperature, current, voltage and concentration the
thickness of the oxide coating may be accurately controlled to give
a high degree of protection against the atmostpheric conditions
prevailing in our enviroment.
As the process is carried out using acid and high temperature conditions,
the product has significant heat and acid resistant characteristics.
Colour anodised aluminium in building and architectural applications
has a proven track record of resistance to outdoor exposure in excess
of 50 years.
The
bottom line is:
A multi-coloured, anodised aluminium sheet that can be produced
on a high volume, repititious level for signs, labels, name badges,
barcodes, graphics, measuring instruments and full colour photographs. |
