Aha! Now you have finally made the distinction in your argument...

Commonly used terminals in the whitegoods and automotive areas (ie. QC crimp
terminals) are indeed made of brass. But that is about the limit of use for this
material. When it comes to electrical crimp lugs, spade terminals etc, then the
lug/terminal material is always copper, unless you are using aluminium
conductors where the terminal material will be aluminium.

Take a look at the Utilux catalogue (small insulated and un-insulated terminals)
http://www.utilux.com.au/pdf/4.pdf and you will see mentioned at the top of
several pages the material is electro-tinned copper. Only the QC tabs are brass.
