maybe tester has more knowledge
I know from looking at the pictures that the frame is fucked and the seller should refund or replace.
6069 is a relatively new (1990s introduction) member of the 6000 series, offering higher strength than the common 6061. Like 6061, it needs heat treatment after welding to T6 (artificially aged) condition to achieve the desired properties. All of which is moot if Mielec use 7005 and 7020, which naturally age harden quickly and can therefore be used for welded structures without post-weld heat treatment.

Robert isn't being cooperative, I am beyond frustrated, if there are any locals still in this form who can help me out, that would be great, I'm trying to get Robert to at least try to claim Polish Post money for damaged shipment (the package wasn't insured btw) but I was told there is a chance for money back by a Polish Post consultant by submitting an online form ... I'm not trying to diy fix this my self because I know I will not get it right
The frame material is most likely 7000 series alu , probably 7005, the frame was built around 4 weeks ago
If someone can help me translate that the inner head tube is also bent, as well as the lip in Polish that would be great, I have tried google translate as well as chat gpt translate, and it seems that Robert thinks only the lip is bent ... Idk why he can't see that the inner head tube is also bent further down... the photos are very clear

I read somewhere it's 6069 T6, maybe @gbj_tester has more knowledge about this material
