Type II PRECISION SULFURIC ACID
ANODIZING
This Finish is RoHS Compliant
( Per Mil-A-8625 Type II Class 1 & Class 2)
Anodizing is an electrochemical process that forms a non-conductive oxide
coating on a metallic surface. When aluminum alloys are anodized an
oxide coating is formed that grows from the base metal and leaves a hard
corrosion resistant coating with excellent wear properties. The presence
of pores in the oxide coating allows the surface to be colored by using organic
dyes and then sealed to enhance its corrosion resistance. The color
of the coating is designated by the Class:
A Class 1 finish
is the natural clear color of the oxide coating
A Class 2 finish is
usually dyed with the color of choice.
Our strict quality control measures will ensure that your parts will be
consistent in color from one order to the next.
* When color matching is important we highly recommend using the same alloy
on all parts.
The oxide coating from sulfuric acid anodizing of this Type II is controlled
to a total thickness in the range .0003" to .0007" or .3 to .7 mils.
