I am planning to simulate a load cell in CAD and was wondering which aluminum alloy are cheap commercial load cells made of? I noticed there is no huge difference between the common aluminum alloys in terms of Young's modulus and poisson's ratio so I assume something like the 1060 and 6061 should not be much different right? Thanks in advance.

  • $\begingroup$ I'm not sure if either of them would be used for a precision measuring device, but at a minimum you'd get more linear range out of the 6061 due to higher yield strength $\endgroup$

  • $\begingroup$ If the Young's modulus is similar across the board, why do you need to know the alloy? Are you concerned about yield strength? $\endgroup$

  • $\begingroup$ I don't think I've ever seen a load cell that was not made out of steel, but that doesn't mean they don't exist. $\endgroup$

    $\begingroup$ @RC_23 they do exist and are actually pretty common. Specially for lighter loads I guess... Thanks for the reply. $\endgroup$

    $\begingroup$ @PeteW thanks for the reply Pete. To be honest I checked the material properties on the CAD software and they seemed not much different for my application. So I guess I will stick with 6061 for now. I will also get in contact with a manufacturer in china maybe and ask them what do they make their load cells from inshAllah. Thanks again! $\endgroup$
