Black Oxide/Parkerizing




Blackened Mild steel is used for 2 industries, the first is for Engineering, There are many products from nuts and bolts, gate hinges, up to engine components that are chemically blackened, to carry out this process you will need a "Black Oxide Kit". this contains 4 products.
1. Degreaser to prepare the metal 2. Conditioner to "relax" the metal and help it absorb the black 3. Chemical Blackener 4: De Watering Oil to seal the Chemical Black into the metal.


This process is typically carried out by diluting the products in to buckets or tanks, and dipping the metal to create an even black finish that is hard wearing. There is a video on the "Black Oxide Kit" page that shows how this process works.  


The 2nd process is for creating a decorative appearance on any items from small objects through to stair cases, desks, restaurant furniture, the list is endless, the process for this is very different from the engineering Process.
Rather than dipping the metal, you apply it by hand, 1. Degrease or clean the metal, removing any mill scale, grease etc 2: Apply Metal Blackener undiluted using a small abrasive scotch brite pad and work it in to the metal, 3. Seal the Blackener in to the metal, depending on the effect you need you can use either a beeswax if you would like an aged Industrial look, Our Caswell Sealer if you need a satin Appearance. or if its going to be used outside a heavy duty clearcoat lacquer.


If you need any advice on the best way to do this please call us on +44 1252 560515 or email us, Our Blackening teams carry out this work around the world, and we have not found a problem yet that cannot be solved, although I must say that to do this work to the maximum effect it is an "Art as opposed to a "Trade", and its not always easy to fit within the building industries "Need it finished quickly" system. if carried out correctly its possible to create a stunning and lasting effect.
