Black Zinc Plated Fasteners

Black Zinc Plated Fasteners

Black Zinc Plating alludes to the shade of the chromate that is connected amid the post plating process. It incorporates a layer of zinc connected to a sections surface pursued by dark chromate connected over the zinc.

Black Zinc is normally indicated for its dim appearance and defensive properties. Dark chromate offers extra erosion insurance by ensuring the zinc plating and furthermore gives a dull to profound dark appearance relying upon the surface state of the part.

Benefits of Choosing Black Zinc

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.

  • Minimize a parts visibility in a final assembled product.
  • Disguise recessed lighting components.
  • Common in automotive applications to camouflage components under the hood or seats.
  • Cosmetic purposes requiring a uniform black finish

 

Considerations

Black Zinc is an effective finish that provides excellent cosmetic benefits to most parts however it is not suitable for every application.

It is common to notice the color change from deep black to greenish-brown as the finish breaks down over time. Because of this color change, Black Zinc may not be the right finish for highly visible components with strict cosmetic requirements.

The appearance can also become compromised on parts requiring a sealer often producing streaks or a dull gray appearance, most noticeable on large flat components.
