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. Paired with an appropriate oil, black oxide adds corrosion protection to parts for storage and use. The sleek black look is a classic aesthetic appeal. Black Oxide coatings add lubricity and reduce friction for moving components as part of an assembly. 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:
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.
