Why Mid-Nite Black oxide your parts?

Because no other process produces more benefits

at less cost!

Mid-Nite Black, magnetite (Fe3O4), is the chemical

conversion of existing metal to form an integral, protective

surface where nothing is deposited, as contrasted to

applying a coating which bonds to metal, but does not

react chemically.

  • Abrasion, corrosion and rust protection
  • Dimensional stability, hardness, temper and surface properties are not altered
  • Retains oils and waxes, improving lubricity, and reduces friction
  • Improves appearance of machined parts. Reduces light glare.
  • Extends shelf life of stored parts
  • Improves adhesion qualities for painting and eliminates dripping, peeling, cracking, chipping or rub-off
  • Suitable for electrical parts as there is minimal reduction in conductivity
  • Cost competitive - even with all of its protection, appearance and performance qualities - its less costly than painting, phosphating or plating.
