Apple launched its new iPhone 7 in September by holding a media event that highlighted its aluminim finish, and it also spoke of a new "rotational 3D polishing" technqiue.

Apple's chief design officer Jony Ive showed a video at the Sept. 7 event that highlighted a new "jet black" anodized finish that demonstrated a polishing method called "rotational 3D polishing."

"The new jet black finish is accomplished through an innovative nine-step process of anodization and polish for a uniform, glossy finish," Apple says in a news release. "An entirely reengineered enclosure results in a water resistant iPhone offering protection like never before against spills, splashes and dust."

Wired magazine spoke with finishing expert Ted Mooney and Robert Probert, the author of Aluminum How To: The Chromatizing, Anodizing, Hard Coating Handbook, about the new process. You can read their comments HERE.

  • Anodizing for Bonding Applications in Aerospace

    Anodizing for pre-prep bonding bridges the gap between the metallic and composite worlds, as it provides a superior surface in many applications on aluminum components for bonding to these composites.

  • 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.  

  • Plating Q&A: Can you color stainless steel?

    Our expert, Art Kushner, says yes, you can color stainless steel, but it is not a process that is typically performed in a plating shop. Read more about his answer.
