Anodizing is a means by which aluminum can be made more durable, decorative and resistant to corrosion. Black oxide stands alone among finishes, both for its unique set of properties, and cost-effectiveness – making it ideal for certain applications.

Hubbard-Hall’s series of room temperature Black-Magic® products use a reactive chemistry to form an appealing black finish on steel, aluminum, and zinc alloys. These essentially dimensionless coatings create a very decorative, durable, black finish that leave an absorbing oxide layer for oils and waxes that will provide for enhanced corrosion protection.

Immerse the part in the mixed Black Oxide Solution and swirl around for between 30 seconds and 5 minutes. Remove the part from the solution and rinse in fresh water. Immediately brush on or dip into the Penetrating Sealant, and allow to soak in the liquid for 5-10 minutes. Shake off any excess and allow to dry thoroughly before handling.

A black oxide conversion coating is applied to ferrous alloys when oxidizing salts react with the iron to form magnetite (Fe 3 O 4), the black oxide of iron. Though standard Black Oxide is set up for steel, it can be done on other substrates including stainless steel, copper, and brass among others. Typically black oxide has a post dip of either oil or wax to improve the corrosion protection of the finish. Black …

Hot Black Oxide involves hot baths of sodium hydroxide (the nasty stuff in drain cleaner), nitrates, and nitrites. Hot Black Oxide converts the surface into Magnetite. The Cold processes produce a similar color, but the coating tends to rub off more easily and offer less abrasion resistance.

Instead, the black oxide coating is produced by a chemical reaction between the iron on the surface of the ferrous metal and the oxidizing salts present in the black oxide solution. These oxidizing salts include penetrates, catalysts, activators and proprietary additives which all take part in the chemical reaction.
