Black Oxide Metal Finishing
Black Oxide is a chemical conversion coating for mild steel, steel alloys, heat treated steels and tool steels. Black Oxide is also available for stainless steel, copper, brass and bronze alloys.
Black Oxide is a chemical conversion coating that penetrates approximately two to three millionths of an inch into steel surfaces. This makes Black Oxide an ideal finish for machined parts with close tolerances. The process creates a deep, black surface with corrosion resistant properties that are enhanced with the addition of a water displacing, oil topcoat. Commonly used on firearms, Black Oxide is both a protective and cosmetic finish for hand tools, automotive parts and machine tools. GunBlack can Black Oxide steel up to 16′ long and process up to 15,000 pounds each day to meet customer demands. With the largest black oxide capacity in the northeast United States, GunBlack has large and small volume customers from Iowa to Maine.
Manganese Phosphate Coating (Parkerize)
Parkerizing is available for mild steel, steel alloys, heat treated steels, cast iron, malleable and ductile iron casting. The Manganese Phosphate Coating results in a medium dark grey finish with superior corrosion resistance.
Manganese Phosphate (Parkerize) is a chemical conversion coating that adds 0.0002 to 0.0003 inches to steel and cast surfaces and provides excellent corrosion resistance. Manganese Phosphate can also be used as a base for subsequent coating or paint. Parkerizing provides superior corrosion resistance, lubricity and resistance to galling. These qualities make for an excellent coating on gears, hand and pneumatic tools, and firearms. Parkerizing is the preferred finish for military weaponry and ordnance. Manganese Phosphate is sometimes referred to as “Luberizing” when using the Parco trade name.
Quality
Our quality is in the color. Both Black Oxide and Manganese Phosphate Coating can be judged by their deep rich color. The better the color the better the protection.
