Question:

A customer has asked us about the feasibility of dying anodized titanium. I don’t think it can be done. My customer claims he has seen colored anodized items. Can you dye anodized titanium? H.S.

Answer:

You are right! The color observed on anodized titanium parts is not obtained by dying but instead is controlled by the voltage and time used during the anodizing step.

  • What is the Correct Anodizing Specification?

    My company fabricates aluminum and steel pedestrian bridge railing among other bridge parts. We recently got an aluminum railing job that called for “Type I” anodizing per MIL-A-8625. There was no anodic coating thickness called out. We are not anodizers and we are at a loss as to how to write up a meaningful anodizing specification for this railing.

  • Test Methods For Evaluating Anodized Aluminum

    Benefits of anodizing include durability, color stability, ease of maintenance, aesthetics, cost of initial finish and the fact that it is a safe and healthy process. Maximizing these benefits to produce a high–performance aluminum finish can be accomplished by incorporating test procedures in the manufacturing process.
