Room Temperature Blackening

Hubbard-Hall’s series of room temperature Black-Magic™ products use a reactive chemistry to form an appealing black finish on steel, aluminum and zinc alloys. These essentially dimensionless coatings create a very decorative, durable black finish that leave an absorbing oxide layer for oils and waxes that will provide for enhanced corrosion protection. The room temperature blackening process offer energy savings and convenience over hot black oxide while sacrificing some corrosion resistance and durability when compare to the finish formed by a hot black oxide process.

Features and Benefits:

  • No dimensional change
  • Suitable for cell manufacturing
  • Increased corrosion resistance
  • Low energy costs
  • Reduced light glare
  • Decorative Finish
  • Provides anti-galling properties
  • Base for organic coatings
