- No dimensional changes
- Dark black color
- Absorbable to wax and oils
- Heat Survivability (up to 900 Degrees F)
- The finish will not chip, peel, flake, or rub off:Black oxide can only be removed by mechanically or chemically removing the finish itself.
- Reduces light glare (reflection):Black oxide makes an excellent finished surface for moving parts such as hand tools and machine parts. The reduction in reflectivity reduces eye fatigue and is less distracting.
- Can be coated for additional protection:Black oxide finishes with supplementary treatments (“after-finishes”) improve the appearance, abrasion resistance, and corrosion resistance of the part to which they are applied. The normal after-finishes are Oil, Wax, Lacquer, and Chromic Seals. The part configuration and the end-use will help to determine which after-finish to specify.
- Improved lubrication characteristics:Black oxidized parts have improved lubricity and anti-galling characteristics due to the after-finish (oil or wax) resulting in smoother running, mating parts.
- No white corrosion:The finished part does not have a “white-corrosion” state as some electro-plated parts exhibit over time. This makes black oxide an excellent finish for parts used internally on electronic components. The small white corrosive flecks are conductive and may cause an electrical short.
- Weldable:Welding black oxided parts does not produce noxious fumes nor hamper the ease with which a part can be welded as may be encountered by welding plated or painted parts..
