Micralox® – microcrystalline aluminum oxide coating

The MICRALOX® family of products offers superior patented aluminum oxide coatings with a microcrystalline barrier that revolutionizes aluminum anodizing with exceptional barrier properties and corrosion resistance over industry leading product life cycles. MICRALOX produces a long lasting, virtually indestructible surface that delivers dramatically superior chemical corrosion resistance and eliminates color fading due to super-heated steam, and is an excellent alternative to stainless steel, plastic and other materials.

Revolutionizes aluminum anodizing.

  • Produces exceptional long life cycles for critical medical device instrument surfaces
  • Delivers dramatically superior barrier and chemical corrosion resistance
  • Eliminates color fading due to super-heated steam
  • Proven particularly effective in high-pH cleaning and aggressive re-sterilization cycles


The definitive coating for many major manufacturers of medical equipment.

  • Exceptional chemical and corrosion resistance achieving up to 10X improvement in in-field performance while meeting all medical product design specifications
  • Replaces conventional anodic coatings with a clear or vibrant colored hard coat
  • First patented IP for new anodizing technology of commercial import in more than 25 years
  • Permanent high-resolution marking and printing capabilities; broad color range/multi-colors on part; suitable for Sanford Print™ permanent embedded identification printing
  • Reusable surgical instruments, endoscopic camera housings, and other reusable medical equipment increasingly require extreme cleaning measures

Sister chemistries: MICRALOX Ultra and MICRALOX Lumina MICRALOX


Ultra Maximum performance for strong alkaline cleaning.

  • MICRALOX Ultra provides 50X the chemical resistance compared to decorative Type II anodizing
  • Withstands high-pH cleaning and sterilization protocols commonly used in European markets
  • Also proven with many other aggressive environments that would otherwise strip conventional anodic coatings and subject the parts to extensive corrosion



  • Clear, translucent oxide provides a perfect balance of breakthrough chemical resistance and design flexibility for medical device applications
  • Can be left natural, or dyed one of nine vivid colors
  • Coatings achieve 16X the resistance in a hot alkaline strip test compared to Type II decorative anodizing
  • Holds up over a life-time of regular cleaning and sterilization without fading, chalking, or corroding
