Colored anodized finishes are created using a progressive
process that builds the finish into the anodize coating.
Processing variables such as anodize tank chemistry, tank
sequencing, voltage, current, time and temperature, as well
as base aluminum material variables such as temper, shape,
geometry, mixed alloys and variance of metal constituents in
an alloy can all affect the final color. The goal is to maintain
the range from color 1 to 3 Delta E. Some colors may reach
5 Delta E or more, depending on these variables. Automated
systems control and monitor products throughout the entire
process, ensuring the most consistent finish possible.
