The black oxide finish makes the metal surface porous enabling it to hold a thin layer of oil.
Black oxide aluminum sheet.
Black oxide or blackening is a conversion coating for ferrous materials stainless steel copper and copper based alloys zinc powdered metals and silver solder.
It is used to add mild corrosion resistance for appearance and to minimize light reflection.
One of the things that makes black oxiding so dangerous is that the black oxide bath operates at about 290 degrees f.
To achieve maximal corrosion resistance the black oxide must be impregnated with oil or wax.
While you can certainly weld black stainless steel you will not be able to grind and or polish the weld.
Our black anodized aluminum sheets are available in gauges of 032 040 063.

The lumiclad black oxide process patent applied for is the first and only high quality method for blackening aluminum that doesn t involve the complexities and high costs of electrolytic black anodizing.
The goal is a weld.
If you want to make a black oxide finish yourself the cold process black oxide system is a safe alternative.
It s the oil that prevents rust from forming on the metal.
We have formed angles from 0 180 degrees and have even hemmed black stainless steel.
It is supplied by the originator of the unique and widely used tru temp low temperature black oxide process for ferrous metals.
Mid temperature blackening processes offer dimensional stability smut free finishes and high quality results.
Room temperature black oxide processes specifically designed for use on aluminum.
The anodized aluminum sheets are recommended for outdoor use because of their fade resistance and can be used in a wide variety of unique design application.
Lumiclad black oxide for aluminum is a durable and attractive black finish that can be coated onto aluminum alloys.
Black oxide is a finish applied to ferrous metals that provides rust protection.
Black anodized aluminum gauge and sheet sizing options.
Epi s mid temperature black oxide process kool blak 225 blackens steel in 30 45 minutes and converts it to black iron oxide magnetite which provides a glossy black finish as well as protection for the part.
Note that this is well above the boiling.
One of its advantages over other coatings is.
While most metal finishing processes use toxic chemicals the black oxide process is especially hazardous and amateurs are most definitely discouraged from attempting hot blackening.
