i see the most difference between the strength and density of these two aluminum alloys, 6061 appears to be stronger.

 

can you weld 6063 ? cus i was told there is some aluminum that isnt weldable is this true?

 

Heres what principal metals says about the two different forms of aluminum...

6061

The alloy has very good welding characteristics and may be welded by all of the common welding techniques. Gas tungsten arc welding is generally used for thin sections (less than 0.032") and gas metal arc welding is used for heavier sections. Use alloy 4043 filler wire for best results, although a decrease in T 6 properties will result.

6063

The alloy is readily welded by all of the conventional methods. Filler rod should be of the same alloy or AL 4043 alloy.

 

And yes some forms of aluminum dont weld to good such a 7475 and 2011.

 

6063 is primarily for extrusions
6061 is your sheet, plate,etc.

 

ok , so that makes sense cus i was looking at some u-bends and they are made from the 6063, one more thing can you weld the diffrent ones together like say 6061 and 6063 ? and thanks guys for the help

 

sorry to throw a wrench into the works, but this comes from my cycling backround. i am pretty sure most 6000 and 7000 series aluminums need to be heat treated. don't know if it would really matter in this case, as i don't know the application, but if you weld aluminum that should be heat treated and then isn't, it has only about 40% of its original strength. The heat treating process brings it back into the 90%s.

let me know if anyone knows anything different.

 

In general terms 40,50 and 60 series aluminum are structurally weldable. 2024 has copper and 7075 has zinc you can weld these also but they will not be structurally strong.

I would not buy o cond metal unless you need to form an intricate part.

You would not nessarily reheat treat a part fabricated fron 6061-t-6 , depending on strength or application. You would need a temperature controlled oven that would go 900 + degrees to heattreat and most people don't have access to such an oven.

 

No the 6000 series do not need to be heat treated, however they need to be preheated for best welding results.

yea, i know they heat treat bicycle frames. You can always ship your peice out to be heat treated if necessary. then again i am talking about weight weenies here with bikes, something that weights around 15lbs. Most of the expensive aluminum frames weight about 2.2lbs for the average rider, and are super stiff. They are extracting everything out of the metal, probably not needed here.
