Conversion coatings on aluminum are coatings for metals where the part surface is converted into the coating with a chemical or electro-chemical process. Examples include chromate conversion, phosphate conversion coatings and oxide coatings on steel and titanium. These processes are used for:

  • Corrosion protection
  • Increased surface hardness
  • Added decorative color
  • Good base for Primers and Paints

Conversion coatings may be very thin, on the order of 0.00001".
