Re: [PSUBS-MAILIST] steel to aluminum

[MerlinSub@t-online.de]

The connect bond bar must be around three times thicker than the wall you want to connect. 
The mid area of the bond is pure 99% aluminum with a low tensile strength. 
Welding process must be very carefull the stuff tends to give way with more that 350 degree C in the center. 
You can not make a pressure tight compartment fom it. 
Because you can weld such a bond pure longitudinal buit not vertical on the conections between two bars. 
And the bars length is limited to around 2-4 meters. 
The stuff is expensive..
