I have a project in mind at work that involves our production PCB's to come into contact with anodized aluminum extrusions. I measured the resistance using the ESD meter we use for our floor/tables.

I did 5 sample measurements of different extrusion's on different machines (so different extrusion suppliers).

• 3 samples were measured between 100-200M.
• The one in the picture that I got here actually measured only 15.4M.
• I found one machine that had extrusions that looked almost like they were painted instead of anodized and these measured >1G.

All extrusions measured (except for the last one) were the standard grey color. The device used for measurement was calibrated this year.

Conclusion: Aluminum extrusions can be ESD safe?

It would be interesting to hear if any of you have looked into this before.
