  • Stainless steel
  • Aluminum
  • Brass
  • Bronze
  • Zinc
  • Exotic alloys

Advantages of Black Oxide Coating

Thermal black oxide treatments provide significant benefits over other types of treatment options. Black oxide coatings are designed to protect the fastener substrate material, while providing a non-sleek decorative finish for all types of applications. Additional benefits that black oxide finishes provide include:

  • Does not significantly change the dimensions of the fastener
  • Less expensive than alternative methods
  • Large run capabilities
  • Oil finish reduces the risk of galling
  • Decorative finish
  • Adds a layer of mild corrosion and abrasion resistance
  • Paint will stick to the black oxide finish, if required

Black Oxide Thermal Coating Processes & Applications

Black oxide thermal finishes are considered a conversion coating, which replicates the surface finish of the part. Before the thermal black oxide finish is applied, a top layer of oil is applied to enhance corrosion resistance. The black oxide is then applied through either a hot or cold process.

Hot Process

The thermal black oxide hot process utilizes different types of chemicals to convert the surface materials into magnetite. The fasteners are dipped into different chemicals, followed by water. An extra layer of oil is then applied to provide further corrosion resistant properties.

Cold Process

The cold coating process does not require the use of as many chemicals at heated temperatures, making it faster, but with less corrosion protection benefits as the hot process. Oil or wax can be applied post cold coating treatment to provide improved corrosion properties.

Applications

Black oxide thermal coatings are utilized for fasteners in a wide range of industries. Some of which include:

  • Automotive
  • Electrical
  • Retail
  • Construction
  • Tools
