General Thickness of a Strong Case?

post #1 of 5
Thread Starter 
Looking at building a case from Scratch get getting a good bit of the cutting done at a CNC.

I'm trying to figure out what material to use, Aluminum or Steel.

And thickness somewhere between 1mm and 1.5MM (20GA to 16GA)

1mm seems to be the norm but its difficult to find these details online for a number of cases.

I think you want to use 14ga for steel, and 12ga for aluminum

Aluminum is relatively weaker/lighter but has better thermal properties than steel. Depends on which alloy you are using (7075 Al is comparable to some steel alloys). 1mm SECC steel is the standard, but those can bend (like computer side panels). 2mm aluminum/steel won't bend unless you like to sit on your rig.

Edit: Aluminum vs. steel shouldn't be based on strength but on the cost of materials/cutting; aluminum is usually a bit more expensive.

If the internals are contructed well, I just want to know if I go with 1mm steel/aluminum that its not going to buckle easily.

1mm feels ideal for me since I can still bend it my self to put the case together, 1.5mm is getting to thick without some 900$ brake.

If your case is just going to sit on your floor, 1mm al/steel is fine.
