Black Oxide Finishes

Metal Blackening and Coating for Iron, Steel, & Stainless Steel

Why should you Black Oxide?

The benefits of Birchwood Technologies black oxide finishes include long-term corrosion resistance and a durable, attractive finish. Unlike paint coatings, black oxide is non-dimensional and will not interfere with function of the metal parts. We offer black oxide in Mid-Temperature, Room-Temperature for immersion applications and liquid or gels for brush-on or swabbing applications.

Our black oxide processes include:

  • Mid-Temperature Black Oxide for Immersion
  • Room-Temperature Black Oxide Finish for Immersion
    (also known as Cold Black Oxide)
  • Black Oxide Liquid for Brush-on
  • Black Oxide Gel for Brush-on or Swabbing

All of our black oxide processes mesh with manufacturing production and easily integrate in-house, cutting lead times, increasing productivity, and saving on finishing costs. We have pre-engineered finishing lines to make implementation fast and easy with a mini-system, 40 gallon line, 100 gallon line, CNC Automated line, and provide conversions or upgrades to existing lines.

Our Liquid and Gel Black Oxide products are ideal for swabbing or brush-on applications for metal touch-ups for machined components, in-place finishing for architecture applications, and artistic or sculpture metal working.

Birchwood Technologies offers free sample test finishing and on-site start up for immersion lines to make blackening your metal easy and successful. Our black oxide finishes work with a variety of metals including cast iron, steel, stainless steel and aluminum.
