200 series aluminum for structural purposes??

Hi Folks,

I am sourcing HEX spacers for a strcutural PCB tower. The only alumium spacers I can find that fit the heights I am looking for, are made from 200-T3 aluminum.

Previously I went by the rule that aluminum could only be used for structural purposes if you use anything above 500 series. However, someone mentioned in passing that this is not true and the 200 series can be used.

Can anyone shed some light on the topic?

Thanks,

Steven

Hi Steven,

As a scientist with expertise in materials science and engineering, I can provide some insight on your question about using 200 series aluminum for structural purposes.

First, it's important to note that the 200 series aluminum alloys (such as 200-T3) are not typically used for structural applications in industries such as aerospace or automotive. These alloys have lower strength and toughness compared to the 500 series, which are commonly used in structural applications.

However, this does not mean that 200 series aluminum cannot be used for structural purposes at all. It ultimately depends on the specific requirements and load-bearing capabilities of your PCB tower. If the 200 series aluminum spacers meet the necessary strength and stiffness requirements for your application, then they can certainly be used.

It's also worth considering the potential for corrosion in your application. The 200 series aluminum alloys have a lower corrosion resistance compared to the 500 series, so if your PCB tower will be exposed to harsh environments, this may be a concern.

In summary, while the 200 series aluminum alloys may not be the first choice for structural applications, they can still be used as long as they meet the necessary requirements and considerations are made for potential corrosion. I hope this helps answer your question.
