Electroplating copper on top of anodized aluminum

Click For Summary

Discussion Overview

The discussion revolves around the process of electroplating copper onto anodized aluminum, specifically Type II anodized aluminum. Participants explore the feasibility of this process given that anodized aluminum is an electrical insulator, and seek methods to achieve a thick and durable copper layer.

Discussion Character

  • Exploratory
  • Debate/contested

Main Points Raised

  • One participant inquires about the method to electroplate copper on anodized aluminum, noting the challenge posed by the insulating properties of the anodized layer.
  • Another participant questions the validity of information found online and requests verification of the source that claims electroplating can be done on insulators.
  • A third participant humorously asserts that anything on the internet must be true, reflecting skepticism about the reliability of online information.
  • Another participant echoes this sentiment, commenting on the self-referential nature of the statement regarding internet truth.

Areas of Agreement / Disagreement

Participants express skepticism about the feasibility of electroplating on anodized aluminum, with no consensus reached on the methods or validity of the claims made online.

Contextual Notes

Participants have not provided specific methods or detailed technical explanations for overcoming the insulating properties of anodized aluminum, leaving the discussion open-ended regarding practical approaches.

Hi all,

I'm looking to electroplate a copper layer on top of anodized aluminum. Type II (sulfuric acid) was used to anodize the aluminum, and everything looks pretty good so far. However, I saw somewhere on the internet that one can electroplate a copper layer on top of anodized aluminum; how would this be achieved as the anodized aluminum layer is electrical insulator? Ideally, I would want the copper layer decently thorough and thick for chemical properties.

Thanks.

Hm ... that statement makes itself inherently true :smile:
