Black Zinc is an electrically conductive finish and offers superior corrosion protection over black oxide. Since the typical thickness is minimal, ranging from .0002” to .0006” it is also a good alternative to powder coat or e-coat for parts with tight dimensional tolerances.

Nov 21, 2022 · Black zinc is zinc plating (say .0002" thick or more) followed by a black chromate conversion coating. You get the sacrificial corrosion protection of zinc, plus a nice appearance, but it does affect the dimensions enough to be a problem on very tight fitting parts.

Jan 25, 2023 · Zinc plating and black oxide are two popular finishing methods for metal components. Both of these finishes can provide a protective coating for the metal, but some differences should be considered before making a final decision.

Black zinc plating is a popular metal finish that provides the underlying component with anti-galling properties and additional corrosion protection. This type of plating is typically applied to parts exposed to high temperature, high wear, and corrosive environments.

Black zinc: this finishing gives a black colored surface to the product itself. It gives better SSL resistance to automotive parts. See below for more info. Blue or clear zinc: This finish offers to …

This finish, also know as zinc plating, zinc chromate or dichromate provides good corrosion resistance and is the standard for many hardware fasteners. It is an electroplated zinc layer covered with a chromate post-treatment.

Jul 13, 2022 · We’ll discuss four: Black Oxide, Black Ruspert, Black Zinc, and Black Xylan. Frequently used on precision fasteners, black oxide is a conversion finish, not an applied coating. Black oxide forms an integral protective surface created during a …

Aug 5, 2021 · Black zinc is a metal plating using either black oxide, actual black plating, or both. With a finish ranging from olive drab to pure black, this zinc coating will provide a more intense rust resistance, particularly when black oxide is used.

Sep 25, 2017 · Choosing GLMF for black zinc plating will give you a deeper black zinc finish, a higher degree of corrosion protection, and a visually appealing plating that is more consistent than other plating companies can provide.

Achieve a highly corrosion resistant surface thanks to ASTM B 633 type II black plating by Novation. We offer dependable zinc plating and other metal surface finishing solutions to provide parts with the rugged exterior they need to withstand harsh environments.
