Aluminum Barbell

I got a heavy-duty aluminum that I plan to use for my DIY concrete weights ill be making,

will the aluminum bar hold about 50-100lbs?

I am on a budget so if anyone tried this before, will the bar bend?

What are you doing with this bar that you only need it to hold 50-100 pounds?

That sounds like a fun, but wholly unnecessary project.

You can get one of those 1.25" training bars for super cheap if they are used. Like $25-40.
