Tech Specs

  1. Corrosion Resistance
    Over 4,000 hours of corrosion protection as tested by ASTM B 117, greatly exceeding MIL-A-8625F requirement of 336 hours.
  2. Accuracy of Desired Oxide Thickness
    Demonstrated conformance to desired oxide thickness within a range of 2-5%.
  3. Process Capability Index (Cpk)
    Demonstrated repeatability with a Cpk of 2.54, considerably outperforming the ISO/QS 9000 requirement for a Cpk of 1.33 and indicating virtually reject-free performance capabilities.
  4. Coating Formation Rate
    A scientifically supported high and consistent rate of coating formation, improved by the ability to run at higher current density without burning.
  5. Wear/Abrasion Resistance
    Taber abrasion of 0.89 mg/1,000 cycles on tested 6061-T6 samples, far surpassing the abrasion allowance of 1.5 by MIL-A-8625F.
  6. Microhardness
    Tested samples surpass ISO 10074 Acceptance Value by 25-30% or more.
  7. Dimensional Changes of Anodized Aluminum
    This data is useful to assist in accurately calculating tolerances on precision parts to be anodized.
  8. Aluminum Buildup Rate
    Field results, supported by lab analysis, indicate better control, analysis, and slower rate of aluminum build-up. Customers previously decanting every 3-4 weeks report a reduction to 6-12 months between decants.
  9. Depth Profile of Wear Resistance
    This finding suggests that the anodic coatings produced with the MLT-III process are very homogeneous and uniform in structure and composition.
  10. Coating Weight and Conversion Efficiency
    General conversion efficiency of 78-97% among a variety of alloys, in comparison to reported level of 61% in conventional anodizing.
  11. Sealing Quality
    Seal tests in accordance with ASTM B 680-80 meet or exceed ISO 7599 specification in all cases.
  12. Current Efficiency
    Current efficiency using METALAST Process is close to 100% in most cases, supporting resistance to burning, higher quality performance, and superior quality.
  13. Breakdown Voltage
    Breakdown voltage testing was performed on the anodic oxide generated under MLT-III anodizing conditions. The breakdown voltage increases with increasing oxide thickness.
  14. Surface Smoothness
    The surface roughness of anodic coatings resulting from the MLT-II and MLT-III processes are analyzed.
  15. Paint Adhesion
    Painted anodic oxides can have excellent paint adhesion, corrosion resistance, and wear resistance. In this study, the paint adhesion aluminum anodized with the MLT-II process and sealed was evaluated.
