Black Oxide
Black Oxide
Hot and Mid Temp black oxide finishes offer more abrasion resistance, for example on steel, the finish is magnetite (Fe3O4). Cold processes offer significant energy savings and less fumes, typically resulting in a copper-selenide black immersion finish that offers less abrasion resistance. EPi manufactures hot black oxide, mid temperature black oxide, and cold (room temperature) black oxide metal blackening chemistries.
Black Oxide applications include automotive, architectural, hardware, do it yourself, medical, machine tool, firearms, defense, fastener, and aerospace finishes.
There are three options for black oxide: Hot Temp, Mid Temp or Room Temp processes. You also need to determine which metal you want to blacken:
-
Steel (including tool steel)
-
Stainless Steel
-
Cast Iron
-
Aluminum
-
Nickel
-
Copper, Brass, Bronze, and White Bronze
-
Zinc
-
Cadmium
-
Tin (cold only)
Besides ISO 9001:2008 certified chemistry, EPi can help upgrade or expand an existing black oxide equipment line, or help install a new black oxide equipment line. EPi provides turnkey black oxide equipment lines for quick and easy installation, including waste treatment and/or ion exchange systems.
