Our 2014 car fuel tank was Al

Thank u so much for your replying and whic series of aluminium did you use for fabricate fuel tank and how much mm or inches thickness ?

Don't want to be an engineer then?

There are many many materials suitable for such a task, Al, Steel, Carbon, Glass, the list goes on and on. It is the role of the engineer designing the system to find the appropriate material based on your systems goals and targets.

I agree with Nick. It is your job as an engineer to at least do some research/work yourself before asking for "the answer."

We used an aluminum that is know for good bend-abilty and low stress formation when welded. Some research on aluminum grades should provide quick answers. Thickness was determined based on our mounting needs and proximity to potential impacts.

Onur Aydın,

You want your material to be formable and have a good weldability. The only trick with aluminum is that you need to have a good welder that is able to weld it, you don't want any leak or weakness on that part of your car.

We once used 3xxx aluminum and it worked well for the application.

As previous members replied, try to figure yourself what type of material would be the best for your application.

3003 aluminum with 1100 filler if your anodizing or 4043 if not will be your best bet. Some things you might not find in books or research is that you cant rigid mount the tank if your using thin gauge material (.040), it will eventually crack even if done in a decent manner. You can use straps made of the same material(3003) that are dzus'd to the frame.

Kevin Parks,
Thank you so much for your directing this site.I'll use the suitable aluminum series.
