I have been registered on this list for a few months and have learned a lot.



I received my 601XL plans a year ago and studied it in detail.  Also watched 

the DVD by Homebuilt.com.



I am going to scratch buildt.  All the aircraft grade aluminium in South 

Africa are imported and therefore quite expensive.  Luckily all the 6061T6 

sheet thicknesses are available from the distributor.



There are local South African 6061T6 extrusions e.g.angles and the flat bar 

for the main spars available but without the quality marking every few 

inches stating it is 6061T6.(Quality markings)



I am working for a petrochemical factory in Secunda, South Africa.  On  site 

is a metallurgical laboratory that is willing to do a physical tensile 

strenght on a sample and confirm the chemical property of the material.(E.g. 

Silicon content)  Otherwise I will have to import the angles and flatbar at 

an enormous price.



However, I want to ask your advise as it is not worth while to take chances 

with inferior materials.



Regards

William,

The parts you cannot get economically probably should be ordered from 

Zenith.  No testing required and some of the bending or special

work may already be done.  You're quite correct about not just taking 

the word of a supplier that materials are of some specific alloy.

Only if they have a good track record with the aviation community, you 

should be inclined to trust them.  I'd suggest you call Aircraft Spruce

and check with them for air freight of the materials you need.

Hi William,



First let me say I am no expert on this subject.  Then let me say it 

seems that 6061T6 should be pretty much the same no matter who made 

it or in what country it was made.  This is a very common alloy for 

aluminum which is used for many things besides aircraft designed by C. Heintz.



Perhaps you could contact the manufacturer in South Africa and ask 

about the quality of this material and how it compares to USA made 6061T6.



I think the manufacturer should be able to convince you that his 

aluminum alloy is just as good as the more expensive imported kind.
