Black Oxide Aluminum Sheet

The hem was an open teardrop hem and there were no defects in the surface of the metal and the coloring was consistent.

Black oxide aluminum sheet.

The black oxide finish makes the metal surface porous enabling it to hold a thin layer of oil. Note that this is well above the boiling. 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. It is used to add mild corrosion resistance for appearance and to minimize light reflection.

To achieve maximal corrosion resistance the black oxide must be impregnated with oil or wax. One of the things that makes black oxiding so dangerous is that the black oxide bath operates at about 290 degrees f. Utilizing a simple immersion tank process line the lumiclad solutions carry out a two stage chemical reaction to form an attractive satin gloss black finish that is tightly adherent to the aluminum surface. Products can be applied using immersion or swab on applications and touch ups.

The goal is a weld. Black oxide or blackening is a conversion coating for ferrous materials stainless steel copper and copper based alloys zinc powdered metals and silver solder. We have formed angles from 0 180 degrees and have even hemmed black stainless steel. Black oxide is a finish applied to ferrous metals that provides rust protection.

It is supplied by the originator of the unique and widely used tru temp low temperature black oxide process for ferrous metals. Our black anodized aluminum sheets are available in gauges of 032 040 063. It s the oil that prevents rust from forming on the metal. 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.

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. Lumiclad black oxide for aluminum is a durable and attractive black finish that can be coated onto aluminum alloys. 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.
