Hot Black Oxides

Hubbard-Hall’s Black-Magic™ line of hot black oxide products is frequently used to produce a true durable black oxide conversion coating on steel, stainless steel, and copper alloys. From the black oxide process, these essentially dimensionless coatings create very decorative, highly durable black finishes that leave an absorbing oxide layer for oils and waxes that will provide for enhanced corrosion protection.

Features and Benefits:

  • No dimensional change
  • Does not affect conductivity
  • Increased corrosion resistance
  • No hydrogen embrittlement
  • Reduced light glare
  • Decorative Finish
  • Provides anti-galling properties
  • Base for organic coatings
