Hi Andy,

Is it the colouring which makes them hard or is the colouring a result of the hardening process?

With A/A badges the anodising stage is totally separate from the colouring one but many consider the colouring of anodised aluminium cap badges to be anodising - this is not so. I can only speak from an A/A cap badge view on this of course and will take board on the processing of other metals with great interest.

Regards

Chris
