I've just checked my order for 6061-T6 sheet with the supplier I intend to buy from here in Australia and have been told they are just waiting for a new shipment to clear customs before they can complete my order. The other supplier I tried to order from told me some thicknesses had a 12 week wait on shipments.



It occurred to me that aluminium is produced here by Alcoa in Victoria... do they not produce aircraft aluminium? So where's it coming from? ...and what standards is it produced to? 



If I'm gonna bank my life on a spar I've built, I'd feel better if I knew the metal was not produced by slave labour in some third world country.



Any thoughts, ideas, opinions? Anyone had experiences with sub-standard sheet?



BTW, when I speak to them next, I'll ask!

Hi Glenn,



Actually, as I understand it 6061-T6 isn't really aircraft 

aluminum.  It is a very common alloy used for all sorts of 

applications including lawn furniture and other mundane tasks.  It is 

much harder(?) than soft pure aluminum which is also commonly 

used.  You will quickly learn to feel the difference between soft 

aluminum and 6061-T6.



The sheets and bars will be marked with the alloy and the 

manufacturer's name.  I have not heard of any counterfeit metal in 

this class.  I suppose it is possible, but this is not a particularly 

expensive alloy.



I know there are plants that make this alloy in the USA and Canada, 

and I am sure there are some in other locations.  All I can recommend 

is you ask your distributors about their sources and if they can 

trust the quality of products they get from them.

True.  It is not the standard aircraft aluminum.  It is reasonable 

strong and has high corrosion resistance compared to 2024.  I do wonder 

why we get so upset about corrosion prevention.  Prior to 1986 most 

light aircraft were not corrosion proofed unless they were set up for 

seaplane use.  I would worry more about intergranular corrosion in the 

extrusions than corrosion in the sheet metal.

My kit had aluminum parts from Canada, Switzerland, and possibly Germany.
