Black Oxide is a chemical surface conversion of metals forming an integral protective surface, while maintaining the dimensional integrity of the part. Along with a post treatment, corrosion resistance of 72 to 144 salt spray hours is possible.

| | Die Cast Zinc Application
Black Oxide provides uniform color with corrosion resistance
at an economical cost.
As the use of die cast zinc components grows, many are
finding applications where both appearance
and corrosion resistance are critical. While organic coatings,
(paint) and plating offer solutions to these problems, the
cost especially for smaller components requiring extensive
handling is substantially greater than that of conversion
coatings such as black oxide.
Cleveland Black Oxide has perfected the process for black
oxide treatment of die cast zinc parts that produce a consistently
dense black finish which adds both aesthetic quality and
increased resistance to surface pitting and corrosion. |
